Trivia / Where's Poppa?

• Blooper: When the naked Sidney is crossing the street to Gordon's apartment, you can easily see flesh-toned tape across his back, hiding some sort of skin condition. When he arrives at the elevator, you can still see a red rash left behind from the tape. His stomach is also completely hairless in the elevator, but it's hairy when he arrives at Gordon's door.
• What Could Have Been: The film originally ended with a defeated Gordon climbing into bed with his mother and saying, "Here's Poppa!" but this was considered far too risqué and was deleted from the final print.
