Goofs--When Zoidberg takes the flag from Old Man Waterfall, Old Man Waterfall's fake hand is the wrong one, unless he has two fake hands.
- It is most likely that every part of Old Man Waterfall's body is fake.
- When Zoidberg has a flashback of his life on his home planet, there are 2 conversations with someone who appears to be his mother, yet in the season 2 episode "Why Must I Be A Crustacean In Love?" it is mentioned at the end that his species dies after the mating ritual.
- On board the Nimbus where Zapp asks for the activation codes for the global defense network, it immediately after cuts to a shot of Kif Saying "Aye Aye sir". In the background of the shot sit two ship crew members, the brown haired one on the left disappears in the following shot.
- In one of the first shots at the Freedom Day celebration in front of the Lincoln Memorial, we see a banner, with the text "Freedom Day - Express yourself. I hate my job.", suspended between to poles. Some of the banner can also be seen during the first part of Nixon's speech. But when it gets time to lower "Old Freebie" (the flag) the banner has disappeared and the flag is lowered into the position where the banner hung before. And the banner was tied to the two poles so they can't have raised it.
Trivia: This is the third role that a member of the Waterfall family appears in, this time "Old Man Waterfall." As with all others, Old Man Waterfall paid a heavy price for interacting with the Planet Express crew, this time getting squashed underneath a huge crab claw. We are also introduced to Frida Waterfall at the end, who will show up again later.
- Dr. Zoidberg runs past several embassies, including a large, pink one. Originally the sign in front said "Barbie Planet Embassy", but once the writers got tired of the joke, they redid the sign to say "Klingon Embassy".
