You can:
Get a cat, go to cracked.com, find a new Xbox, play the old games you neglected because of your Xbox, slap a pigeon, grow a carrot in a shoe, find a lizard then throw it at someone, use your new free time to download huge files for the heck of it, learn to play the ocarina, read Shakespeare's complete works, play around with chemistry, study, spend quality time with friends/family, lick something you wouldn't lick otherwise, burn some ants, sculpt something, acquire a taste for modern art, watch every South Park episode, discover new music, read the replies to your post, fight a dragon, watch Bruce Lee movies, watch Tengen Toppa Gurren Lagan, learn to twirl a pen, write a book, harass Starbuck's employees, build a flamethrower out of a super soaker, BUY a flamethrower (legal in the US), learn to ride a unicyle, write a poem, start a blog, read Raven's Dojo the webcomic, beat Super Mario world
AND
Make a wall of text list on the escapist, much to the dismay of others.
I bet no one's gonna read the whole thing, though...
