In terms of stupid consuption challenges I once drank a gallon of Mountain Dew (why? because my cousin's wife said I couldn't, OK? I showed her etc etc...) Please, all of you, promise me you will never attempt this foolish act.
In terms of my last day, I'd probably spend it going over Niagra falls in a barrel, listening to In A Silent Way and prank calling James Hetfield. I might even have a lager and lime if I were feeling saucy.
Oh yeah, and Kerouac is balls, my dad bought me a book about him for Christmas (here son, you're a teenager, I think...) and that's balls too.
There's a really lovely Bukowski poem about Horses.
