Numb3rs (2005)

Prime Suspect - S1-E5

Continuity mistake: When Charlie Epps is writing a quadrillion on the whiteboard, the writing alternates between shots. Most noticably when he first writes it down, there is a significant downward tendency of the 000 groups. In the next shot, they are pretty much horizontal. Also the shapes of the commas alter.

Alan Eppes: Ah, I'm just a little nervous.
Terry Lake: Don't worry-everything looks wonderful. In fact, your son could learn a few things from you. Know where we went on our first date?
Don Eppes: All right, all right, all right, all right.
Terry Lake: The laundromat. Dinner was pizza.
Don Eppes: A little professionalism.
Alan Eppes: You don't say... How interesting.

Trivia: Judd Hirsch is an astro-physicist and can actually do the math Charlie does on the show. He caught the acting bug in school and chose that over physics.

In Plain Sight - S2-E8

Question: This question is about the mistake where a SWAT officer has a magazine backwards in his MP5. I know this would be impossible on a real weapon. But, how could it have happened in filming? Rubber cast weapon? Very badly worn prop weapon? Set armourer with a hammer and no clue?
