Let's see...
Laughing at a certain friend when he tries to tell me something in Pokemon sucks (like Scizor supposedly does because Escavalier is apparently soooooooo much better) or doesn't work/exist (like the RNG), or the fact that he believes Regigigas is the greatest Pokemon ever.
Finding a shiny Pokemon.
Holding in a major shit because I'm in class/can't go to the bathroom, then letting it loose in a public restroom.
Correctly predicting the next song on shuffle.
Getting extremely wasted, playing Super Smash Bros, and still beating my sober friends.
Beating an extremely difficult challenge on a video game (like anything to do with Shao Kahn on Mortal Kombat 9, especially that bullshit challenge 251).
Waking up early on week days to watch The Match Game on GSN.
Pizza, especially chicken bacon ranch.
