The Peruvian Puff Pepper - S3-E2
Other mistake: Drake and Josh find the monitor in Megan's room. After they reveal the normal wall and the family leaves, Megan hits the button behind the picture to show the monitors. However, when Drake and Josh find out that Megan entered the salsa competition, they storm into her room, but the button is still revealed in the background.

Continuity mistake: If you look at the kitchen table after the salsa exploded; you can see no salsa on the kitchen table.
Audio problem: Drake starts playing his electric guitar while Josh is doing his homework. His guitar sounds amplified, even though his guitar isn't plugged into an amp.
Continuity mistake: When Josh throws the piece of fruit (or whatever it was) to break the lamp, Audrey checks out the lamp stand. In the shot where Walter first arrives and she's checking it out, it's all in one piece. But in another shot, it's suddenly all broken and a big piece is missing.

Character mistake: Drake says he hasn't been in Megan's room since he was five, but he brings Grammy's bags up there in the episode "Grammy".
Continuity mistake: Near the end, when Josh whacks the thug with the bat, the thug falls to the floor and his hat flies across the floor. In the next shot the hat has moved closer to him.

Revealing mistake: In the scene where Megan puts the stuff in the salsa and stirs it with the spoon, she takes it out and it is clean, then Josh stirs it again and the spoon comes out clean again.
Continuity mistake: When Megan is passing out the pop quizzes, she reaches back with her right hand to hand them to the kid seated behind her. But in the next shot, showing the kid she is handing them to, her left hand is holding the quizzes. (00:13:10)
Visible crew/equipment: In the scene that Drake and Josh return to their room with B-a-a-a-b, the lamb is startled and jumps off the couch. As Drake is running to catch it, a crew member's hand is momentarily visible waving on the left side. (00:20:25)
Revealing mistake: When Josh says "I do not look good in pink panties" in the intro, he looks down below the camera at what we can assume is a script. He also cracks the tiniest smile near the cut, which is breaking character, as he was angry in that moment.
Factual error: Josh said he's been waiting 15 years for a girl to kiss him, but in a previous episode, Drake's girlfriend kissed him.
