NSFW - This trivia is considered "Not Safe for Work" - Click to Reveal
In the Coffee Shop during the "Free the Sperm Whales" mission, heading into the bathroom, selecting the Foot and clicking on all 3 screws on the broken mirror and then on the skull drawn on the side of a stall will trigger a secret cutscene. Butt-Head will pull out a shotgun, say "$&*@ you Beavis", and shoot off Beavis' head. Butt-Head will then call him a "dumbass" before cutting to the title screen.
