Continuity: In the episode when Drake joins the Academic team just to impress a girl, look at the scene when the academic game starts. For about a second, before the announcer starts talking, the Belliview scoreboard says 1. Then immediately flashes back to zero.

Audio problem: In the episode where that man tries to eat Drake and Josh's orangutan, after the guy runs away Megan pretends to leave and she starts stomping her feet, then when Josh says, "Wait!" she stops stomping her feet, but you can still hear the stomping sound.

Audio problem: Ep. 2-18 "Drake and Josh Go Hollywood" - Near the end when Drake is playing Hollywood Girl and gets into the bridge (the steady drum beat part) you can obviously tell he's mouthing the words.

Factual error: In 4-41, "The Wedding": In the scene where the tow truck guy crashes the car window, notice the glass goes in the car. Later the glass is there, but Josh sits in the car without being cut by it.

Revealing: In the episode where Josh becomes equipment manager, when he leans against the wall with wet paint on it and gets paint all over his shirt it is clear that he is not actually leaning against the wall. This is especially noticeable the second time he does it.

Other: In "Helicopter", when the dad has some of the "soup", he eats it with a slotted spoon.

Continuity: In 4-47, Tree House, in the beginning when Megan shoots Josh with the rubber band, watch after Josh drops the books. Notice it next to him on the couch. After Megan leaves, the rubber band is gone.

Revealing: In the episode 2-18 Drake and Josh go Hollywood, when Meghan peeks through that slot thing at least two of the bad guys look straight at her.

Continuity: In the episode "Eric Punches Drake," Drake spits in some guy's water bottle. After he does this, the liquid inside the bottle is clear mixed with a little blue. But when it shows the guy's water bottle again, it contains a nearly opaque blue liquid.

Revealing: In the episode 4-38, Josh Runs Into Oprah: When they are in the hospital and Drake says "We'll go now," right before he says that, the guard on the left side of the door from the view shown flashes a small grin.

Continuity: About halfway through the series, Drake and Josh's door changes from facing the camera to facing the right (the other direction).
