Woody Woodpecker in Mall Rats

When Silent Bob is placing the VHS tape of Shannon's encounter with Tricia in the VCR, the crossed out title is Woody Woodpecker.

Mallrats is a 1995 American buddy comedy film written and directed by Kevin Smith and starring Jason Lee, Jeremy London, Shannen Doherty, Claire Forlani, Ben Affleck, Jason Mewes, Joey Lauren Adams, Michael Rooker, and Smith as Silent Bob. It is the second film in the View Askewniverse and a prequel to 1994's Clerks.

This is the most minor of Cameos and goes by really quick. It's nearly impossible to see unless your screen is big and you play the movie in slow motion.
