Back in college, I had a roommate that was a competitive sharpshooter. (He had boxes of trophies and 'perfect' targets.)
He had never, not once in his entire life, eaten or drank any product that had added sugar, or any amount of caffeine. (It helped that the had vegan parents.)
Well, he lost a Superbowl bet one year. (He bet against the Cowboys) His penance? He had to drink an entire 2-liter bottle of Jolt Cola
in a one-hour span.
If I hadn't been so afraid that he was going to have a heart attack, I would have laughed my ass off. He was, quite literally, bouncing
off the walls. He could not stop moving for about six hours. He could not stop talking, either. And he was normally a very
reserved person. About two hours into it, the bet winner tried to get him to shut up by offering him $50 if he could be quiet for 60 seconds. He didn't have to give up the $50, because he couldn't even be quiet for 10 seconds.
Looking back, it's hilarious. But at the time, I honestly had my hand on the phone for most of the time, expecting to have to call an ambulance to come revive him from some kind of internal organ explosion.
Ironic, considering his subdued-ness, he DID drink (and often binge on) alcohol. He said that the 'Jolt Hangover' was significantly worse than any alcohol hangover he had ever had.
He is now an Air Force pilot. (Not sure what kind, but I do know he's a pilot.)
