Based on your username, I like to imagine Mr Magoo is a 70 year old boomer, who masturbates to source material that he claims is just vanilla pictures of naked girls. Then you, as the viewer, see what he's been masturbating to, and it's nothing "bad", but it's clearly a whole OTHER side to Mr Magoo's kinks. Just a whole bunch of femboys, and gender swapping porn. Again, not judging.
But the humor would come into play trying to figure out if Mr Magoo is actually the homophobic hateful person he claims to be, and just has bad eyesight (again, it's Mr Magoo, so it's plausible), OR does he secretly know EXACTLY what he's wackin it to, but uses the old hateful man image to cover his reputation if anyone discovers it?
I'd watch that show. Why can't Adult Swim own the rights to Mr Magoo? They owned the rights to space ghost in the mid 90s, and said "Here, go nuts. We don't give a fuck."
I feel like anyone who has one of these would exclusively use their mouth to blow this boy. It might be hard, you might get light-headed, but by god you'll stick through until he's done!
