For many many years I was a critical care medic. One of my great pleasures in the job (aside from helping people :P) was getting a new guy during a full arrest (CPR). We would have 3-5 people working the code, and when I saw that things were under control and the new guy was able to break away for a second, I'd look him dead in the eyes, and yell "Grab the henway! We need it quick!!"

He'd then spend the next 30 seconds tearing the truck apart looking for the henway, thinking he should know what and where it is, and not wanting to look bad and asking. Eventually he'd give up, and ask "What's a henway!?"

And I'd say "About three pounds!"

The look on their faces as you can see their brains just vapor lock at that answer, at that moment, was priceless.
