D.P and Skeeter, also known as the Frat Aliens, are two blue aliens that belong to some unnamed, outer space college fraternity. They are both voiced by Patton Oswalt
D.P. is the dumber one who constanly mentions that his "dad owns a dealership". In the episode Frat Aliens, his frat brother Skeeter stranded him on Earth. D.P. annoyed Frylock and Meatwad, but Master Shake liked D.P. when he got drunk. D.P. is a nickname, which he says stands for "Donkey Puncher", a.k.a., "D to the P" and "Donkey Puncherello". His real name is unknown as he is unwilling (or even unable) to give it.
Skeeter has more common sense than D.P. His real name is Zarnold Edward Quigley, which he despises.
