Freudian Slip? I'll Say!

You know when they say, when moving into a new place, check all your appliances to make sure they work before you need them? Yeah, I didn't do that so found myself shivering when the temps dropped and the furnace didn't work. (Blankets, blankets and more blankets!) When the maintenance guy showed up he quickly diagnosed the problem. Now, I know what he actually said but I swear, with his accent (English was not his first language) what I heard was, "You need a heated coupling" and all I could think was,

"Dude, you don't even know."
