Continuity mistake: In the season 3 episode "The Crack Fox," just after the crack fox sucks some of the shaman juice up in his needles, his hand is suddenly out of the bottle and there is no green juice in his needles. And when the crack fox is fighting the homeless man, the needles suddenly have green juice in them.
Revealing mistake: At the very end Vince is DJing with the cobra, and when the cobra starts dancing you can see the fishing wire attached to the snake to make it move.
Continuity mistake: Bob Fossil records Howard saying "Gorilla" on his talk box, which Howard does with a downward inflection at the end of the word. However, every time Fossil plays back Howard's "Gorilla", it has an upwards inflection at the end of the word.
Continuity mistake: For most of this episode, Vince's hair is blonde-brown. However within the tent and with the polar bear, it is red brown. This is because the footage for this scene was taken from the pilot.
Continuity mistake: When Naboo drops the necklace on the floor, in the wide shot when he turns around and disappears, the necklace disappears from the floor too, but then a few seconds later, Vince sees it and picks it up.
Continuity mistake: There's a scene with Vince and Howard in the van talking with a bear in the back. Vince says 'watch this' and starts to eat a candy snake, the snake is half eaten, then the shot cuts and it's nearly gone between shots.
Continuity mistake: When Kodiak Jack is showing Howard his scars, he pulls his right sleeve off to show the moose bite. But in the next shot and for the rest of the episode, his right sleeve is intact and it's his left sleeve that's missing.
Continuity mistake: When Vince is putting sunscreen on, the cap of the sunscreen bottle changes from closed to open between shots.
Continuity mistake: During the crowd scenes at the party there is a girl with a blonde bob cut and a pink and black leopard print top who noticeably and dramatically changes places between shots. A good example is when Howard is giving his speech and she is at the front of the crowd, then suddenly appears on the complete opposite side of the room next to Vince's bedroom door, and then appears in the middle of the crowd, dancing.
