There should really be a "Worst Travesty committed on Last Comic Standing" poll or something. I'll start the list off:
1) Dat kicking off Dave
2) Ralphie kicking off Rob
3) The fact that the acts are cut short
3) Geoff lasting so long
4) Cory helping Dat's sitcom
5) Hide-and-seek 'game'
6) Seeing Rich and Dave half-naked.
7) The phrase "Right on, cha-cha-cha"
