Continuity mistake: When Jimmy is in his lab, in the shot where the camera zooms into his eye, in the shot just before that shot, notice the digital clock on Jimmy's counter. The seconds part jumps from the 30's to the 40's twice in two different shots.
Continuity mistake: When Jimmy and Cindy first arrive on the island, Cindy's shoes are grey. But earlier in the episode and later, they are pink. Yes, she was soaked with water from the ocean, but it should've made the pink on her shoes only a darker shade, maybe even red, but not grey. (00:04:59 - 00:16:16)
Lights! Camera! Danger! - S3-E3
Continuity mistake: When Jimmy and his friends are falling from the top of the building, they are all wearing sunglasses. However, before they're about to hit the ground, only Carl has his sunglasses on. When they get back on the roof, they're all wearing sunglasses again. (00:08:43)
