Many sitcoms have catchphrases that stay with audiences forever, but these are catchphrases you want out of your head as soon as you hear them.

"Up your nose with a rubber hose."

"Sit on it."

"Kiss my grits."

"Nanu nanu."

"What you talkin' about, Willis?"

"Dy-no-mite!"

For me, it was definitely the one from Newhart: "Hi, my name is Larry. This is my brother, Darryl. This is my other brother, Darryl." How funny. Not!

"Up your nose with a rubber hose."

"Sit on it."

"Kiss my grits."

"Nanu nanu."

"What you talkin' about, Willis?"

"Dy-no-mite!"

Agree with all. In addition:

"Stow it."

"That's what she said."

"You got it dude."

"Ayyyyyy."

i really hated the sit on it catchphrase
