A Heterosexual Brojob

Listen up, you absolute goof. You think you're so clever, posting your little jokes online? Well, let me break it down for you, you smooth-brained twit. The joke plays on the idea that an action can change a person's orientation. It implies that the gay act transforms the straight men temporarily to gay, even though it's not really how things work in reality. It's funny because it's absurd, kind of like your jokes... which are not funny.
