Bullet to the back of the skull.
Just toss me naked into freezing water. The shock would keep me calm until the drowning really set in, then it would be all peaceful and stuff.
I second the guillotine. Either that or a firing squad. Could I request they be Marines in dress blues? With a drummer?
Guillotine for me, too, complete with a tumbrel ride up Broadway and a speech on the step of the scaffold. Then, just as the blade fell, I’d make a funny face so I’d get a laugh when the executioner held my head up for the crowd.

Guillotine, as long as the blade’s REALLY sharp. I’ve always wondered how long a head can stay alive sans a body.
I’m fairly certain Cecil did something on this. Yup, here it is .
My choice would be to drink hemlock from a cup made of the hollowed-out skull of the judge who condemned me.
I think I’d go with a good old-fashioned beheading. As long as the blade is extremely sharp. I’m inclined to think it would be almost completely painless, despite how it looks. Although I have no doubt the brain is “alive” following decapitation for at least several seconds, I imagine the sudden, extreme drop in blood pressure will cause nearly instantaneous unconciousness. Works for me.
Off with his 'ead!
Wasn’t someone in England drowned in a vat of his favorite wine? That sounds like a fun way to go.
I’m cool with any method that involves me, three beds, massive amounts of vitamin E and sildenafil citrate and at least 40 nubile teenage female virgins.
Darling, you don’t want virgins- virgins expect you to do all the work. What you want are WHORES. See, you’re gunna die before the infections really set in anyway.
When I was younger and angrier, my typical response was, “Give me two pockets full of pennies and a skyscraper and we’ll all come down together.”
I revised it to guillotine, but now I see it’s not very original, so I’ll have to revise it again.
For those worried about the sharpness of the blade, don’t. The weight and momentum are enough to make up for any dullness.
Death by either alcohol or caffeine poisoning for me, thanks.
Freefalling pennies have a very low terminal velocity. Too low to hurt anyone. They aren’t stable falling edge-on and wind up tumbling instead. 
Highly elaborate and ceremonial death by firing squad :).
Hmmmmmm. That’s a startlingly good point. Okay. HALF whores!
Hey, I don’t go around smashing your old angsty teenager dreams, do I?
George, Duke of Clarence, brother of Kings Edward IV and Richard III, was supposedly drowned in a butt of Malmsley wine.
I think the most painless way to go would be to be at ground zero of a nuke. Of course, it wouldn’t be terribly safe or cost effective for society, but one millisecond you’re just fine, and in the next millisecond you’re nothing but vapor (or is it plasma?).
