Mr. Derp cameos in the background when Garrison returns.
When Mr. Garrison is talking to the Police Chief about his missing penis, a framed photo of a child who looks remarkably like Stan can be seen hanging behind the Police Chief's desk. The boy is not wearing Stan's hat, but his hair is similar to Stan's whenever his hat comes off and he is wearing the football jersey and number that Stan wore in "Big Gay Al's Big Gay Boat Ride." Whether this was intentionally done by the writers or if it is simply a coincidence is unknown.
