A sad mistake it was to make and doom him to this vile lot...

At the water cooler:
Cow orker 1: What were you for Halloween?
Me: I was a pirate. Laziest costume I've done in years.
Cow orker 2 (just walking up): You were what?
Me: A pirate. For Halloween.
Cow orker 2: A pilot?
Me: No. Erm. ARRRR! (makes hooking motion with crossed fingers)
Cow orker 2: Oh! I see.

Now I have Pirates of Penzance in my head.
