Goof: The episode claims that one of the symptoms of smallpox is a swollen tongue. There is no such symptom for smallpox.
In the episode "Plague" Both Hotel rooms IE: Pam's room and Bill's Room Are room 127. Apparently they could only afford one room and used the single room and shot them at different angles.
Skydiving is clearly used for the fall scene, and the guys are like 10,000 feet up. Last time I checked, helicopters don't go that high!
You can see the reserve parachute on Ralph's leg while he catches the falling Bill.
Bill: I know, I know how you feel, I do! Nobody wants his tongue to swell up and turn black, throat to close up on 'em, spinal column goes into spasms and locks, you die in a cold sweat. Nobody wants that!
Ralph: (terrified) THOSE ARE THE SYMPTOMS?!?!?!
Ralph: Happiness is a warm pistol? That's a nice piece of American tribute.
Bill: Yeah, I know isn't that terrible. I told them pistola and they left the 'a' off, the creeps!
Bill: No I'm not! I'm a great liar!
Bill: You know Villicana, they got this terrific youth authority up in the mountains. They got swings, and a slide, teeter-totters, and 200 hard case morons for you to play with.
Tony: My man Maxwell! You know just the other day I was sayin' "where is that great buy Maxwell?" He hasn't been around much.
Bill/:President of my fan-club!
Bill: I want this case! I like it a lot! I eat bugs for breakfast!
Ralph: Bill, are you OK? What's wrong with your knees?
Bill: Fear. Or... I'm drunk.
Ralph: No, you're not drunk.
Bill: Then I'm alive!
Bill: Thank you, Ralph. Thanks very much.
Original song, performed by Joey Scarbury: "Don't Let Me Down". Appears in the scene where Ralph saves Bill after he's dropped out of the helicopter.
