My supervisor wasn’t in yesterday.

Coworker: Think he’ll be in today?
Me: I don’t think he’d miss two days in a row without telling all of us.
Coworker: Want do you want to bet on it?
Me: Pizza if he doesn’t come in.
Coworker: Ok *plays message of boss not coming in*

I’ve been snookered.  I learned a lesson today: Never trust dwarf Vietnamese CAD designers.
