for a guaranteed laugh, randomly use the words:
"Whatever your favorite cheese is."
"Ding Hay Ding Fifteenski."
"Look how spit my thick is."
"DUI? D U You."
"See now, that's psychotic handwriting."
"The geek family: 'We just keep poppin' 'em out and bitin' their heads off.'"
the Cool end
* either both cool AND uncool or neither cool or uncool
