Was Bebbete ever seen? We heard about her in "Jack Gets His" from Larry who said:
"She'll have to put on more then a coat!"

I don't remember ever seeing her. I don't think we even got to see Greedy Gretchen until towards the end of the series.

Greedy Gretchen was in #106 "Lies My Roomate Told Me" and in an episode of "Three's a Crowd"
