EDIT: I'm a fool

Spongebob Squarepants, the Cop, has received a report that he, himself, is guilty, which indicates that a Driver has used both of his night-actions on Spongebob Squarepants.

I can't provide photographic evidence, but in episode 752 the first five minutes show spongebob on his coralpad playing epicmafia. At exactly 3:24 right before Gary bothers him you see his role as baker.

The President provides evidence of Spongebob Squarepants playing a real and interactive Mafia game:



Here, in this photographic proof, Spongebob Squarepants, the Lawyer, testifies to Fish Man, the Cop, that his partner is innocent and should be stated so in the police report.

Assumptions can then be made that Spongebob Squarepants has also played other variants of Mafia, including one possibly on this very website.
