Mourning Wood

Alright, listen up, you smooth-brained buffoon. You posted a joke about a necrophiliac, which is a person who is sexually attracted to corpses. Do you have a habit of hanging out at morgues? Probably. Anyway, the punchline plays on the phrase "morning wood," which is an erection that men experience in the morning. Here, it's changed to "mourning wood," because necrophilia is, like, a big no-no, and usually associated with death and sadness. Get it now?
