I’d kill some terrorist or dictator - bin Laden, Castro, Hugo Chavez, Kim Jong-il, etc. That’s assuming I could start the 24 hours just before I get to them so I’d have a chance to get away.
So many of them, so little time.
I’d go hide for 24 hours. No way would I let anybody know, in any fashion, nor would I do a thing with the power. Then I would try to forget it ever happened, and never mention it to a soul.
Heh, this sounds verbatim like an old Twilight Zone episode.
If I were Black I’d go to a KKK meeting and tell those fuckers what I really thought of them.
Or as some one said above; Make lots of Bar bets.
I’d jump off the Golden Gate Bridge. It’s morbid, but I always think that that would be an amazing view. Maybe I’d put on some kind of flying-squirrel suit and see if I could glide to Alcatraz or something. In fact, that’s probably all I’d do. Climb a bunch of Really Fucking Big things. I wonder if I could get to Dubai in 24 hours’ time?
I agree, if I was invincible AND it wouldn’t hurt, I’d try things like walking around underwater, or running through fire (even if my clothes burnt off), just because the experience would be so unique and otherworldly.
I don’t think even aliens could convice me I was invincible, unless they did something to me involuntarily that I know would kill me under normal circumstances. And while I wouldn’t suggest to them that they prove it to me, dropping me out of their ship in orbit and letting me re-enter the atmosphere, free-fall to Earth and walk away would go a long way toward proving I could survive other things.
I wouln’t go to the bottom of an ocean, as I could see getting stuck there until I was vincible again. I wouldn’t go around killing dictators, as there are too many security cameras around them for my comfort.
So I too would basically stick to high stakes bets. Hmmm, how would this work with erections? Clearly I couldn’t get friction burn – if Viagara would burn through my system in less than 24 hours, I’d take a bottle of it, go into the fanciest bordello I could find, and challenge a house full of talented hookers to try to take down Mr Winkie. 
I would hope that it is the day of a Space Shuttle launch. I would sneak in and ride that bitch all the way into abort from the outside. After casually bailing off and falling back through the atmosphere, I would aim for something like the White House or the Vatican where I would run around squealing like a little girl as they shot me over and over. Cart Wheels would add to the effect.
I’d get an excellent camera, and go down to the bottom of the Marianas trench, for at least twenty-one minutes.

Fire. Lots and lots of fire.
That is the most hilarious image I’ve had enter my mind in a week.
Thank you.
I’d ride in the crazy sky gondolas here. Table Mountain, Magaliesberg, here I come. As it is, I have such horrendous vertigo that I thought I was going to die of a panic attack on a zoo gondola, and that thing was maybe 20 meters off the ground.
So, I would ride a sky gondola high up onto a mountain. I’d like to be really adventurous and say that I would then jump off, but invincibility or no, I’m still really a big chicken.
I’d walk face first into the spinning prop of an airplane, just to get warmed up.
Then I’d walk over to a jet, getting ready for take off, and let one of its turbines suck me through.
I’d duct tape myself to the side of the space shuttle, and take a ride the likes of which have never been seen… then I’d float around in orbit, right in front of the windows of the shuttle, and feign a choking expression, with bulged eyes, holding a sign that says, “Reno or Bust”. Then I’d shove off entering an unstable orbit until I reentered earth’s atmosphere, and make a crater somewhere at Chuck Norris’ place.
Then I’d kick Chuck Norris in the balls.
After that, I might eat a banana for lunch.
Then back to business.
I’d take an afternoon stroll. On the highway. In the opposite direction. In the fast lane.
With luck, a semi would stike me the right way, and launch me 40 feet and onto the service drive. Where upon, I’d buy some .45 rounds. Then I’d go into another gun shop and ask to see one of their pieces. I’d hastily load it, then shoot it off in my face. Until it was empty. Then, look at the gun, nonplussed, place it back on the counter, and say, “Damn thing’s broken.”
And for the finale, I’d strap all kinds of class B, display fireworks to my body, and light them all off in unison, as I saunter through the mall, screaming the lyrics to, “My Country, 'Tis Of Thee”, as I’m banging symbols together.
If there was any time left, I’d head over to Hawaii, and take a relaxing swim in a lava flow… you know, to wind down from the busy day.
Then I’d stick my hand in the running garbage disposal to cap the night.
Watch out, Baltimore, there’s a new sheriff in town (one day only).
Invincible as in nothing bad can happen to you as the result of your actions in that 24 hours, or invincible as in “The biker gang you called pussies will not hurt you today, but there’ll be a knock on your door tomorrow when the invincibility has worn off”?
I’d either steal atomicbadgerrace’s idea, spend the time following Shagnasty around, or–assuming I would have unending stamina for that 24 hours along with the invincibility–run at top speed in one direction for 12 hours, then turn around and retrace my route at top speed for another 12 hours. Save myself all that boring “getting started on a fitness routine” crap.
Or invincible as in the gunshot wounds don’t do anything today but tomorrow you’ll bleed out and die from them?
The Op specified Physical Immunity, so I’ll go with nothing can touch me, but I might have to pay for social actions later.
I would go and grab a costume from the magic shop and begin my reign of terror as “Don’t be an Asshole Man”. Assholes all around the metro Orlando area would quickly learn to quake in terror from my fearsome retribution. Since I am invincible, and in disguise I have little need to fear the authorities. In fact, some of them might be due the Smite of Just Retribution. My goal would be to correct as much asshole-ish behaviour as possible with as much media exposure as possible. If all goes according to plan, people should be marginally nicer to each other around here, for a little while at least! Hopefully I will spawn innumerable copycats as well.
There’s gotta be a “turn your enemy into your chum” joke in there somewhere, I just can’t fish it out.
I’d make James Randi pay up on that Million Dollar challenge. I’d ask him how many times he’d need me to jump off a building to ‘prove’ my supernatural invulnerability.
Hey, at least I’d get SOMETHING out of it.
Lovely image, but you’d be stuck in orbit longer than the 24 hours. It takes a major change in velocity to deorbit yourself quickly.
I like this one! What symbols would you use? I’d bang an ankh against a Biohazard symbol.
What would I do? Well, if the legal immunity is for real, I’m tempted to say that everybody would wake up the next morning to President Pelosi. Thing is, though, I still believe in the system.
