A Guy in a Lab Coat appeared on Dinosaurs in the third season episode "Charlene's Flat World." This greatly respected dinosaur works as an engineer for the WESAYSO globe department.

When Charlene is put on trial for claiming that the world is round, the "Guy in a Lab Coat" brings one of his (flat) model globes as evidence against her theory. As if that is not enough proof, WESAYSO has a warehouse full of those things.
