Necrophilia and Cold Ones

Listen here, you absolute troglodyte, you think that because something is cold that it's the same as a dead body? You are a special kind of stupid. The joke is playing on the phrase "cracking open a cold one," which usually refers to opening a can of beer. The dark humor comes from comparing this innocent act to the act of necrophilia, which is something completely different, disgusting, and not at all fun. Get a grip, you goofball.
