oh man this is a hard pick for me bc i like so much of the show... the first thing that comes to mind is in lawnmower dog when they're on the plane and rick resorts immediately to islamophobia its so bad it just feels so out of place

thats probably the only one i have such a harsh reaction to. i do also hate the scene where they recruit elon tusk in one crew just bc i hate him. that one is more tolerable bc its preceded and padded by mr. poopybutthole hephaestus and ventriloquiver, all of whom i find to be quite fun. also he cuddles with hephaestus at the end of the ep
