The Great Egg Heist/The Feud - S2-E9
Other mistake: In the Great Egg Heist, when they arrive at the museum, Jimmy gives everyone shishkabob-shaped earplugs for Libby's scream. But in the next shot, if you look at everyone's ears, there are no earplugs. Also, in the next shot, next to Libby you can see Carl putting his hands over his ears. This is impossible because the pointy ends of the earplugs would stab Carl's hands.
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.
Sheen: Jimmy, where's the bathroom? All I see is sand and I'm not a cat.
