What happens when "Big Brother" legend Jessie Godderz runs into his favorite TMZ photog?
This time, the answer is DUCT TAPE HAIR WAX -- a punishment for not staying up on "Mr. Pec-Tacular" ... and the reality show that made him famous.
Jessie flipped the script on our guy at LAX, serving up 3 questions in an impromptu pop quiz.
Our guy only got 1 ... and the former pro wrestler wasn't about to let him off the hook.
Silver lining -- this was the LEAST painful of their encounters ... which have included a submission beatdown and manhood-crushing wedgie.
Better brush up before next time!
