Johnny Depp at Kmart Clearance Rack

Listen here, you chucklehead. You think this is just random? This joke plays on the term "wife-beater" which is used for a style of white tank top. Kmart is a discount store, and they are trying to clear out their stock. By putting Depp on the rack, it is implied that he is being "sold" too. The joke also references the Depp's recent public trial for allegations of domestic abuse. It's a dark joke because it makes light of a serious accusation.
