Happy Days reference on Seinfeld?

I recently heard that there was a Happy Days reference in a Seinfeld episode where George and Elaine were talking about a friend of Elaine's and George wants to know if she likes him.

George: What did she say about me?

Elaine: She says she likes you.

George: Does she "like" like me?

At this point, Jerry becomes disgruntled and says to Elaine, "Well, if you and Potsie are done now, I'd like to leave." --------------------------

Does anyone which Seinfeld episode this in? Or of any Seinfeld web sites that would have a .wav file of this scene?

Thanks.

i don't recall the exact episode, but elaine and her friend are sitting next to each other in a drawing class discussing george. elaine is caught chewing gum by the teacher and has to spit it out. the other girl said george is a cool guy.

I don't know about that one, but in another episode, Elaine and George are sitting on Jerry's couch hatching some kind of plot, and Jerry says to Elaine, "If you and Potsie are finished scheming...."
