Trivia: When Wong drains Flamingo Lake to water his golf course and the flamingos are sucked down the plughole, in amongst their startled squawks you can hear one yelling "SH*T!". Listen for it - it's very clear.
Trivia: When Zapp Brannigan tells Leela to surrender by waving her shirt in the air, there is a shot of Leela pulling her shirt off whilst the camera pans up and we see a shot of her breasts for a few frames. Confirmed on the Audio Commentary. However neither of her breasts have nipples; possibly as a result of her being a mutant. (00:59:00)
