Role in episode
Before the health inspector can take a bite out of the Nasty Patty, he chokes on a fly and slips in condiments, smashing his head on the table and breaking the chair he is using, knocking him unconscious. The fly then flies out of his mouth. Seeing his unconscious body, SpongeBob and Mr. Krabs think they have killed him. Upon seeing this, they attempt to bury him. It is unknown what happened to the patty. However, because the health inspector never really took a bite from the patty, it is unknown what could've happened to him if he did.
