Fastest Criminal in Reno - S3-E5
Continuity mistake: When Fast Eddie jumps over the road block and comes crashing down you can see from the severity of the landing that the front left side of the vehicle is seriously damaged as is probably the rest of the front of the vehicle.

Beauty and the Obese: Part 1 - S1-E1
Audio problem: After the bartender himself offers a lap dance to the man who just talked to Persephone, the man walks off to the right of the screen. The bartender offers him a cheaper price when the camera cuts to a different angle after he walked away. At this point, the man would now be just off the left side of the screen, but when you hear him say "No" it comes from the right side when listening with headphones. (00:02:42)
