Father O'Leary is featured in a cutaway gag set up by Stewie in "Gronkowsbees".
When Brian suggests he can turn his beekeeping hobby into cash by selling honey at farmers markets, Stewie notes that he feels like an eighth grader that just had sex.
As the student brags to his friends, they demand proof, which is displayed as Father O'Leary's underwear. The Father is shown crying in a stall at his 'secret' being exposed, believing it was going to be kept out of love.
