Pizza Guy

The Pizza shirt guy or That Fat Guy is a background character in Gravity Falls.

History
The man first appeared in "Headhunters" watching the re-opening ceremony of Grunkle Stan's wax museum. When Shandra Jimenez points out that Stan promised free pizza on the advertisement flier, and Stan says it's a typo, and flees with the admission money, disappointing the audience. The pizza shirt guy sighs and sorrowly walks away. Later when Dipper Pines and Mabel tries to figure out who's left-handed so they can figure out who's the murderer of Wax Stan, they find the pizza shirt guy and gives him a package, then asks him to sign a paper. The man signs with his right hand, and Dipper leaves with the package, much to the man's disappointment.

The fat guy appears next in "The Hand That Rocks the Mabel" watching Lil' Gideon's presentation at the Tent of Telepathy. He also appears in "Dipper vs. Manliness" at the Greasy's Diner. When Dipper figures out a plan to help win Wendy a stuffed animal at the fair, he throws the ball above the pins, and it hits the fat guy's face
