I was thinking about this for a while, and I think it would be neat to have a list of all of the movies/games that fancy pants man has appeared in as a cameo. I am not sure how many there are, but I can think of two from the top of my head.
Riddle School 3 - in the principal's office at the end of the game, there is a fpa poster.
Blockhead episode 10 - in the background of the part where there is a close up of 4 eggs on a table
has anyone found any other cameos?
