"Hey, Charlie, we got a weirdo out here!" ~ Grover
Those Waiter Grover sketches have some great lines, indeed.
"Singe an itty-bitty, Charlie!" ---Grover.
This later becomes... "Okay Charlie! BROIL THE BIGGIE!!!" (from the big and little hamburgers skit)
"He O'fainted." ---Grover (from the fast food skit)
"That does it! From now on, I'm bringing my lunch to work in a paper sack." ---Mr. Johnson (from the chicken soup skit)
"In a hurry to be fed, beady eyes and big blue head!" ---Grover
"I DO NOT HAVE BEADY EYES!!!" ---Mr. Johnson (from the waiter's memory skit)
