Mongobert, show JoeMagoo and Juggalobert some respect. Joe is destined to save the world on Independence Day when the aliens will come to invade us. JuggaloBert, on the other hand, is a poor slob who was flashed by a defective neuralizer after having given his best years in M.i.B.
I've seen some back-to-back comments exchanged between JoeMagoo and JuggaloBert in the previous strips as well. Both look like PHB's distant cousins and I strongly suspect that they are the same person with split personality syndrome :P
