There was another episode where they had "Ladies Night" at one of the clubs Fred/Barney were working at, and the guy at the door asks Wilma who she's with, and she points to Betty and says, "I'm with her." Followed by Betty's, "It's ladies night isn't it? Well I'm with her."
There was also anther episode where the Water Buffalo's thought Fred was setting them up a strip show, whereas it was really a beauty pangent for babies that Pebbles was entered in. One of those guys asks, "Are we going to see girls in a bikini's?" and Barney replies, "No, we're actually going to see girls in diapers." The guy says, "Wowee, I didn't know they posed like that! Yahoo!"
LMAO. And of course Pebbles and the other babies crawl out on stage instead of adult women.
