Scooby-Doo! Camp Scare
A doctor told Shaggy to take a rest from solving mysteries after the last one sent him into a state of one continuous scream (for hours). The gang had found a spa resort, but Shaggy also wasn't allowed to get in the Mystery Machine either, so Fred painted out the word "Mystery" with "Mustard".
