Will Ferrell
You can never tell if Will Ferrell is joking. So when he asked for an electric scooter, a flight of stairs (on wheels), a fake tree (also on wheels), and a prop rainbow (weirdly enough, also on wheels) the venues just obliged as best they could. They probably didn't have to bring any of these things to Ferrell, but he's happy they did.
Larry the Cable Guy
Larry the Cable Guy requests exactly what you'd think he requests. He asks for 50 hot wings from Hooters, and four cans of berry-flavored chewing tobacco. He's not the healthiest man on Earth, but that's his gimmick anyways.
