Character mistake: Tina Fey fumbles her line and has to start it again. The original line should have been "How long do you think you're going to get away with this? Hazel or Jenna will know we're missing." Instead the second part of the line is "Henna or Jay; Hazel or Jenna will know we're missing!" (00:04:05)
Character mistake: When Kyle is re-taking the test at the end of the school day, you see him bubble in 4 answer and turn the page and continue to answer questions. However there were 7 questions on the first page so he ended up putting the answer to #8 on #5 of the scantron. Kyle is too smart to do this.
Character mistake: Louis Greene, Masuka's new intern, is asked to find the person who purchased Rudy's prosthetic hand. He is unable to do so; however, as a consolation, he says "I installed a modded-up Intel chip to overclock your CPU." You can overclock your CPU, but you don't need another chip to do so. (00:44:00)
Suggested correction: Only K series intel CPU's can be overclocked so a CPU upgrade is understandable if the previous one was not overclockable.

Character mistake: When Olivia turns up at Jackson's house, she says, "That was my Saturday afternoon. This is my Saturday night!" which indicates it is the same day.

Dedication - S1-E7
Character mistake: When they show the helicopter containing Alpha team, it is a Bell 206 JetRanger, and the sound effects match it, but Brown says "This is the first time I'm on a Huey." The Huey and JetRanger look and sound nothing alike. (03:25:00)
God Is in the Details - S2-E10

Episode #5.6 - S5-E6
Character mistake: When Alice is releasing the cape vulture at Mara, she twice says "good boy" to the vulture, which means that the vulture is male.
