Not funny.

"Get off."

It happened too fast, and I wasn't ready. One unsuspecting victim, me, of sudden physical proximity.
It was probably a joke. He knows better; his aim isn't that bad anymore. He lands square in my face every time.

So I'm pretty sure he did this on purpose. His grasp of humor isn't the greatest.

"Seriously, get off me, Cas."

You don't just go landing on top of a guy in the shower.
