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.
Visible crew/equipment: In the garage scene, Drake hands Josh the baby to see if the baby needs changing. After Josh has sniffed the baby, he falls backwards onto the floor. The black crash mat that he lands on can momentarily be seen in the bottom-left hand corner of the screen.
Revealing mistake: When Josh is telling Drake that Mindy told him she loves him and when Josh slaps Drake near the end of the scene, it is really obvious that Josh is slapping air. His hand is at least 6 inches away from Drake's head and yet they play the sound effect for a slap.
Visible crew/equipment: After Josh breaks the guitar strings he sits on the couch. When Drake asks him where the party is and he says the brew note, Drake says 'this day keeps getting better and better." You can see a reflection of a light used by the camera man in the small window behind him.
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.
Continuity mistake: In the scene where Josh tries to prove Susan is cheating on Drake with him, after Drake comes out of the closet the camera is facing him and the right side of Josh's shirt is on his right shoulder. In the next shot, it's hanging off his shoulder. When the camera faces Drake again, the shirt is back on Josh's shoulder. In the final shot, the camera is facing Josh and the shirt is hanging off of his shoulder again and he fixes it.
