Dude I was 18 when I experienced "Tequila Nirvana".
LOL, my buddy Caulder and I were at a party, and it was kinda boring, so he grabbed a bottle of Cuervo and challenged me to a shot contest. The guys on the board that've met me can attest that I'm 6'4", about 220lbs, and drink a lot (I'm Irish, roll with me).
So, anyways... We get up in to the early 20's in our shot count, over the course of about an hour or two. We're both completely fucking drunk on this kid's patio, a bunch of tore up limes in between us and the wood bench / table that we're sitting at is just fucking covered in salt since now we can't even hit our licked hands - we're just throwing salt wherever we think we can get at it.
So he takes shot 21 like a champ. I take mine. We pour out #22, and he basically goes pale. He slurs that he can't do it. He's on the brink. I'm staring at #22 and find the courage within me. I take the shot. I am the champion of the universe.
So, about 30 minutes later, my girlfriend is holding me up while I'm puking my insides out over my toilet. I pass out, satisfied that I'm the champ. The next day my buddy calls me (the one that was having the party) and starts cursing at me... Turns out that Caulder (my tequila competitor) ended up walking in to the bathroom, whipping out his wang, and pissing all over everything in the bathroom, and then passed out in the bathtub with his junk in his hand and puking on himself to boot.
Great times!
