The Dumb Guys' Convention was a convention that was held for dumb people (hence, the name).
Guess Phil's Name
Guests had to guess a guy (named Phil)'s name, but, never got it right, despite the fact Phil was wearing a nametag,and they had already told them the guys name.
Jumping off a 5-Story roof into a "Swimming Pool"
Guests literally jumped off a building, but there was no swimming pool.
- Stephan Pastis originally was just making a dumb guys' convention without Pig, but, because people might've complained due to the absence of characters, he tried to put Pig in each adventure.
