My dad walks in as it's coming to an end, and one of the cooks is going on about how greatful she is to be kept on for the next show and not booted off, because absolutely everything was going wrong for her, so it's a pretty emotional moment.
My dad, who has not watched any of the show, just comes in and hears her prattling on and blurts out, "Ah, shut the fuck up."
It was said offhandedly, but I was *this* close to going off on him, for being rude to the person on the show, and to those of us actually trying to watch the show in the room.
I decided it wasn't worth it. But I still needed to vent. =P
