Try reading the OP again:
hmmm… I guess I could bet Lance Armstrong that he couldn’t beat me in a race around my block.
I could re-up my pysch. meds. They don’t seem to doing anything… 
Or even to be doing anything…
:smack:
Enormous sushi dinner for me and my hubby, then spend the rest of what’s left on skeeball. Oh crap, I’d get tickets for skeeball, wouldn’t I? Ok, sushi for me, my husband, and two of our friends. That should do it.
$300, eh? Nothing to show for it at the end of the day, eh? Based in Texas, eh?
So tell me, SHAKES, … are your initials GWB?
You’re all missing the point. Everything mentioned has some benefit to it. Me, I’d pay a homeless person for his collection of blue. Not blue anything, just blue. And maybe a little yellow.
I’d spend the day before drinking water without going to the bathroom.
The next day, I’d walk right into a city council meeting, and take a good relaxing whiz on a city code book.
Use the 300 bucks as bail.
Full body massage
pedicure
manicure
eyebrow waxing
hair cut and color
A pamper me day :::sigh:::
I guess my op could also read: **“What’s the most frivolous or irresponsible way you would spend $300 with out having anything to show for it by the end of the day?” **
Come on guys. I’m not get’n that old am I? I thought everyone’s seen “Brewsters Millions”. 
Lots.
And lots.
Of really.
REALLY.
Good.
Booze.
Nitpick: Unless you do not spend that money there will ALWAYS be something to show for it. If you split up the money you have a different ammount then you did before: something to show for it. If you were to go to eat steak there would be one less steak in the world, more dishes to wash at the kitchen of the restaurent, and probably the transaction in a record book of some kind: something to show for it. If you were to go to a stripper bar you could possibly change the way a stripper’s underwear is fitting by stuffing wads of cash up um, there would also be a tab from the drinks I would suppose you would be hammering, and there would more than likely be less DNA in your body and more on your hands when you were done with the evening then you had started with: all things to show for your actions. Since you paid for those things then you have left a trail and made some noticable dent in the universe no matter how small. Redefine your parameters, perhaps?
I’d take my sweetie to Dodger Stadium and get 2 tickets in the new field level box behind home plate. (150$ a pop)
-300 $1 hookerbots, or 1 $300 hookerbot?
-Commit a crime with a $300 dollar fine
-Eat 3 $100 dollar bills, in front of a crowd of impoverished ghetto children
-walk up to a random stranger, and say “I’ll give you $300 if you say the word ‘wristwatch’”
-Get a Civil War era rifle, use shreds of the bills to wrap the bullet.
-Buy a $300 speaker, throw it off a balcony. Leave the broken electronic parts where they lie.
-Buy $300 worth of antimatter, and place it in contact with the air.
Well, Jeesh! I didn’t know I was going to need a Masters Degree in physics just to get the jist of my post accross. I guess I’ll enroll in MIT and come back in eight years or so to make a post that’s a little more understandable or not quite so vague.
What did I do wrong? From the OP I got that the main thing was to blow the money on something fun…no charity and no bills. I would easily spend 300 dollars on a trip to the mall, Tower Records and the auto parts store.
[…sigh…] Yes, I know that. That’s why my original answer fit the OP’s request even though the OP himself violated his own rule. But several intervening posts took the question to be something akin to “how would you blow a million dollars?” with every response leaving something to show for the $300. So… I made a sarcastic posting that, in light the preceding threads, I would invest it and give it to charity. It was a jab at those who were ignoring the OP. Dang. Jokes aren’t funny when you have to spell out the punch-line. 
Lib, surely you were being sarcastic too when you said “I would have nutrition and an erection” to show for my spending spree.
[shrugs shoulders] I don’t know I thought it was quite obvious I meant nothing of monetary value.
Aw c’mon c’mon…Shurely you mean walk up to a random babe and say “I’ll give you $300 if you get your top off”
Because at the end of the day you’ve increased your posessions by a couple of CDs and some X-Box games. The purpose is to spend the money on CONSUMABLES AND SERVICES.
Looks like my $300 anaesthesia wins - Save for a small bump where the needle went in, I won’t have even a memory of the event, let alone any tangible items or lasting effects on my body.
(A massage doesn’t count as it does leave you with some lasting benefit!)
Wrong. There is only 1 post prior to yours that incorrectly read the rules (Barbarian’s paying off some membership dues). All the other responses perfectly fit into the rules proscribed by the OP (per the example of the movie Brewster’s Millions).
SHAKES, your guess is as good as mine as to how you could have been any clearer.
