(It's Episode 3 season 1 "Spring Broken", after the IMP met Verosika but still before they went on Earth. Verosika "stole" Blitzo's parking spot for a week and so Blitz challenged her to a Fucking... Challenge, she and her crew will have to fuck more people that he and the IMP can kill)

Your GF comes back home and she seems really pissed off, you know what that means... Blitzo...

"That Little... Oh Hey Babe, guess who the Fuck I've met today at my new Parking Spot?"
