Not a T-shirt

I'm at work.
I'm wearing my hat that matches this shirt:I'm even cataloging, for a change.

What are the odds that the staff actually leaves me alone?

[So far I've hear The Clash, Carlos Santana, Jimi Hendrix, Melissa Etheridge, and Don Omar in the headphones....this could be a good day....if people don't mess it up!]
