Guy Fieri Mom's Shaghetti 1.25" Pin
This pin requires a fair amount of background information in order to get the joke. If you don't know how to properly pronounce the Mayor of Flavortown's last name and you are unfamiliar with the lyrics to "Lose Yourself" by Eminem, then you're out of luck.
If you're one of the select few that can mentally assemble this puzzle, then my hat goes off to you. Now buy the pin!
