4. Jack washes his own mug.

Ianto groans as he pokes around Jack's office. So far, he's found the combination to the safe, a few notes addressed to the captain that are much older than they should be, a veritable civilization of dust bunnies, and a file of inappropriate films. But no mug. Now, he's under Jack's desk, searching under it. He slides his hand into a hard-to reach crack, only to be desturbed by footsteps. Ianto starts to jerk his hand back, but he hears a snap!, followed instantaneously by hollow thud!, and he yelps in pain. "Ianto?" Jack has an uncanny knack for catching him in awkward situations. For example, when there's a mousetrap stuck on his hand. "Just so you know, I rinsed out my mug myself today." Ianto feels oddly grateful as he fights back the urge to kill his boss.
