Deliberate mistake: When all the thumbs are at the wall saying "I'm the king of the globe" and "I'm a dentist" you cannot see their legs, so that saved some costume work.
Continuity mistake: In 4th black's move, king's bishop go to third row (A3) and capture the white knight. There is not elipsis yet, but. in 6th black's move, Geri's imaginary opponent takes a piece from A4 to B3 and capture a white pawn. but there wasn't any piece previously on A4, in fact, pawn was not moved before, staying on B2, its original place. In the next shot black bishop remains on A3 and white pawn on B2, as nothing was happened.

Audio problem: During the dream sequence in the song, Lulu begins swinging from three different stars depicting 3 different faces of celebrities at the time in black and white that have their lips moving with the song as they sing.

Continuity mistake: When Daffy enters Bugs' living room wearing a rabbit costume, you can see the door is plain green. But when Elmer Fudd enters to confront Daffy, the door is now divided into three sections.
Audio problem: When the lion walks on stage, the audience becomes completely quiet and all that can be heard is the sound of the lion's voice. Behind him is only a curtain that hides the orchestra from view. Once he finishes speaking, he turns around and the curtain opens, and suddenly you can hear the orchestra doing sound checks on their instruments and it is loud, the lion tapping his podium to quieten them so they know the concert is about to start. This means merely a curtain was keeping their sound check from being heard at all until it was open? (00:02:25)
Continuity mistake: When the inebriated cuckoo pops out of the cuckoo clock at the beginning of the short, his feet are yellow, but when we see a close-up of the cuckoo in the next shot, his feet are now orange.

Other mistake: In the opening credits, Manuel Perez's first name is misspelled as "Manual."
Continuity mistake: Once Spunky is kidnapped and Hunky takes off chasing the truck, you see the truck going along the road passing just some grass and one large rock on its left side. Once Hunky catches up to the truck, it cuts to a side view close up of him and Spunky's head sticking out the back, and suddenly the truck is passing a very large rock that was not there in the previous shot. The rock is taller than the truck, so it would have shown. And then it's very obvious the background is then looped as the same huge rock passes the truck every few seconds repeatedly. (00:01:35)
Continuity mistake: When Bugs is standing in front of the General's desk, the General has nothing in his left hand but in the next shot he is now holding a pencil.
