Blackmail Iguana Bob: The player character can discover that Bob's "iguana bits" meat is actually meat from human corpses supplied by Doc Morbid from Junktown. After discovering this, the player character can blackmail Bob into giving them money, or say that they are going to tell the police about it.
The following is based on Fallout cut content and has not been confirmed by canon sources.
It seems, however, that the true nature of the "iguana" meat was not spread very far, as eighty years later (around 2242) Son of Bob's Iguana Bits prospers in the New California Republic, where his son, Mikey, owns the stand.
When trying to blackmail Bob into paying you, one of the dialogue options is to say "Prime Choice Select is made of people!!!! It's made of people!!!" quite loudly. This is a reference to Charlton Heston's famous line from the movie Soylent Green.
