Continuity mistake: At the beginning of the episode when Bill goes into the booth there is a guy that walks out, he is seen walking down the stairs twice.
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.
Continuity mistake: When Lisa is helping Joe with the test he gets her a soda, he puts it on the table she then moves it. It is right next to the can of peanuts. Lisa is seen moving the can of peanuts back, there is one shot that shows it now behind the can of soda, then the next shot they are again next to each other.
Visible crew/equipment: In the opening scene when Joe walks away from the table, the shadow of the boom mic can be seen on the wall.
Continuity mistake: When Lisa and Dave are talking about lunch in Dave's office the coffee mug on Dave's desk changes position.

Visible crew/equipment: When Dave leaves his office after Matthew gets hurt a boom mic can be seen.

Continuity mistake: When Jimmy wipes off the dry erase board with his sleeve he does not get all of it, but when he goes to write on it is completely clean.
