Best lines by others than the NY four

One of the things that amaze me on Seinfeld is the quality of most of the supporting cast or actors and actresses that only appear once or twice on the show. In any case watching "The bottle deposit 1" tonight I couldn't help but laughing when Tony replies to Jerry:

-"THE WASHING FLUID IS NOT FINE !!"

There are NUMEROUS examples of these in the series so if anyone feels like it, just add them.

-Mo

"Maybe 'cause we're both WACKO"

"The surgeon left a sponge inside me."

"This guy's BONKOS!"
