space crew takes woman away from native cave man:
“Darn jocks taking away my girl, I’m going to leave the chess club.”
As a group of prehistoric natives appear with spears, Joel sings (to the tune of the Monkees): “they’re too busy spearing, to put anybody down.”
Prehistoric man’s name is Tang, cut to a kissing scene between him and Linda (space crew member): “Wang/bang, thank you Tang.” (By the way, there were numerous joke references to Tang the breakfast drink, you gotta believe!)
“Dont just do something, stand there!”
“Yeah, you two disposable characters, wait here.”
Man falls into swamp, gurgling heard….”Is it primordial soup yet?”
Crew is walking through the jungle, Joel shouts, “Gilligan, Skipper, Wrong Way, Japanese guy (two characters that appeared in one Gilligan’s Island episode) Actually; I take that back, Wrong Way appeared in two episodes.

I agree with R8. I don’t like Larry (Joel Weinstein) as the voice of Tom Servo at all.
