Continuity mistake: When Paris was on the phone to Janet in the Gas Station (the episode where they work at the gas station and meet "Chops" and co) it cuts to a shot of the fat boy standing next to the same phone and the receiver is put down. It then cuts back to Paris using the phone.
Continuity mistake: While Mike is cleaning out the armadillo's hay, just before he finishes the second one you can see the amount of hay in the bin is a few inches from the top of the bin. The next shot goes to a close up of him removing more hay but the amount of hay now in the bin is a bit below the top.
Continuity mistake: During the police car challenge, Richard Hammond is taking his homemade police car around the track on a timed lap (with extra points for flamboyant driving). As he rounds the Hammerhead corner, the makeshift stinger (that's a spike strip for the colonials) on the front of his car breaks off and is left behind. He then drives through a stack of boxes, getting one caught on the remains of the stinger mounting. As he approaches the second-to-last corner, the box has gone and the stinger is now back on the front of the car. In the final shot as his car limps across the finish line, the stinger is once again missing and the box has returned. Clearly footage from a different lap was substituted in. (00:51:10)
Leaning, Lobsters and Lectures - S1-E11
Continuity mistake: Buddy is doing a lobster themed cake for a bachelor party. When Buddy goes in to tell the staff, there is a huge cake 3 tiers high being worked on, almost complete, on the table in the background. As he makes the parts for the lobster cake the cake in the back has fewer tiers, no decorations, no icing, and back again, completely out of order.
Continuity mistake: In the episode where they overhaul a 1976 blue van, there is a shot of the white donor van being carted away. Yet later on in the same episode, the white donor van is back in the workshop.

While the judges are explaining that three of them did not impress, a shot shows Sarah Miller standing to Clint's right, but she wasn't supposed to be there. In the next shot, Jesse is standing to Clint's right. (00:38:20)

Continuity mistake: Van on the Blue Team is asked to leave Hell's Kitchen by Chef Ramsey and is shown walking out. Soon after, when the Red team is nominating team members for elimination, the camera shows Nick on the Blue team and Van's Head is in the shot.
