In one of the show's major running gags, Red often threatens to punish Eric with many variations of the catchphrase, "my foot in your ass" or more generally "kicking your ass." For example, in "Kitty and Eric's Night Out", Red mistakenly thinks Eric offended Kitty, so Red says, "I swear I'll kick his ass!" In "Eric's Hot Cousin", Eric tries to get out of something by claiming he's sleepwalking and Red says, "And I'm about to be sleep-kicking your ass", and, in "Prank Day", when Red gets covered in oatmeal, Eric tries to explain that it was just a prank that had gone "horribly, horribly wrong" Red says, "Well, I have a prank, too. One where my foot "doesn't" plow through your ass. Let's hope it doesn't go horribly, horribly wrong!" Several of the running gags were shown in edited clips for the series finale.
