Character mistake: S44/E80 Noah Newman works as a bartender, and while at Victor Newman's house says "let's show off some of those drink serving skills." While making a drink he pours straight vodka from the bottle into a martini glass and puts in olives and hands it to Abby to drink. As bartender Noah should know how to make a martini. He doesn't use any vermouth with the vodka and doesn't chill it first by shaking or stirring it before pouring it into the martini glass. (00:11:00)
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.
