Multiple layers of it in a single short conversation. First, Happy asks Chubbs why a guy his size isn't playing a "real sport" like football or something. (Carl Weathers, who played Chubbs, used to be a pro football player). Chubbs answers the question by claiming that his mother wouldn't let him play anything dangerous. Happy comments that maybe that's a good idea. (Weathers also played Apollo Creed in the Rocky movies, who died in the ring during the fourth film). Then, Happy discovers that Chubbs is missing a hand, and in Predator Weathers' character had an arm cut off just before being killed.
The character of Mr. Larson is referred to as 'Frankenstein' at one point. Richard Kiel who plays him was in a Monkees episode as a 'Frankenstein' type creature.
Awesome, Dear Boy: Bob Barker wasn't interested in the extended cameo until he was informed he would win the fight against Happy (he was actually friends with and trained by Chuck Norris).
Beam Me Up, Scotty!: Some people, particularly The Price Is Right fans, think Bob Barker says "The price is wrong, bitch!", even though it was Happy when he thinks he's beaten Bob in his brawl. After the fight, Bob says "Now you've had enough... bitch."
Chubbs is played by Carl Weathers, who was featured in the Rocky films as Apollo Creed Interestingly, like Apollo, Chubbs dies, only he falls out of a window after seeing the one-eyed alligator's head.
The script called for an immediate scene transition after Happy slugged Barker, but then they got the idea to turn it into a full-blown fistfight instead. Initially, Bob Barker didn't want to appear in the fight against Happy until he was informed he was going to win it.
