Character mistake: When talking about poker Jimmy asks Dave "What are the chances of getting five of a kind of the same suit?" The most you can get is four of a kind and they would be all different suits.
Suggested correction: Jimmy says "in the same suit" which is slightly different than "of the same suit." It was just a weird way of saying the odds of getting a flush. Lisa replies with 504.8 (the odds of getting a flush). In poker lingo, 3 or 4 of a kind is taken to mean same value since 3 or 4 cards in the same suit isn't anything.
Suggested correction: Five of a kind is possible when using one or more wild cards, such as Jokers.
