Can anyone tell me why the president in episode the girl who cried gnome has a hanger in his suit

I think it's a symbol of the president's higher rank of stupidity, among the other idiot earth monkeys.

Because he's stupid.If he has a hanger in his mouth it obviously means he has no brain.I'm surprised he can still speak.

maybe he just forgot to take it of the hanger =-L
HE STUUPID X-D

Because he was in a hurry to get dressed.
No, just kidding.
It's a misceláneo sort of a thing to signify the stupidity of Earth Monkeys in the show, especially the president, even más than they have before. For humor and randomness.
