Goodo and Jobo are characters that, despite their demonic roots, have a naivete about things, allowing them to see mundane things -for us- as this amazing and magical and weird strange things.

Like mistaking a feather duster for an actual chicken for their rituals.

And on that note, yes: Jobo is REALLY well hung. He used to be a LUST demon back in the day… before he was demoted to whatever he is now.
