Come on guys, you just don't get it. Quinton knows spending large amounts of money on stuff a normal functional adult would never buy makes him look creepy and retarded, but he's doing it ironically! Therefore it's super funny and entertaining. It's definitely not creepy at all when he keeps the sex doll in the background of a bunch of his videos and shows it to his parents, because Quinton's merely pretending to be a creepy retard.
I mean, it's like you guys know nothing about how youtube comedy works. When you have nothing interesting to say and most goldfishes have more personality than you, you can just compensate for it by making wacky, zany irresponsible purchases.
