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.

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.

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.

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.

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

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.

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 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.

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

Visible crew/equipment: After Josh falls out the buggy there is a shot of him lying on the floor in which the crashmat he landed on is visible under the buggy.

Visible crew/equipment: When Drake and Josh first get into the dune buggy, there is a person under it.

Continuity: 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.

Continuity: In the beginning after Drake asks Josh, "what guitar do you think would look best." He opens up the cabinet and paint squirts his face. At first it only squirts his forehead, but when it switches views you can see his whole face is covered.

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.

Continuity: When Josh is trying to pull off the phone from the base the phone gets thrown across the room in the fish tank and breaks. Then about two scenes later the phone is back on the table fixed up.

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: During the scene in the science classroom, the teacher draws a circle on the chalkboard and refers to it as a picture of the human eye. In following shots, this picture constantly changes from having other parts like irises and pupils to just being a blank circle.

Continuity: When Drake dumps out the snacks on the table with Josh's puzzle on it, he knocks the puzzle box off the table, but when Drake says "The mean man is gone" the puzzle box is back on the table.

Continuity: At the beginning of the episode, while Drake sits on the bed with his guitar, the strap falls down off of his shoulder. In the next shot its back up on his shoulder again.
