LOL: Office air horn prank

(CBS) - It started like any other Monday. Get in to work, have a seat at the desk, crank up the Pedrito Fernandez, start going through the bills. But then, things take a turn for the worse. Who could have foreseen... the office air horn prank?

Not this guy, that's for sure. It's always hilarious when life imitates cartoons. Seriously, he falls out of his chair and his hat flies off? Classic. Classic office gag. In unrelated news, it may not be a bad idea to wear headphones for the rest of the day... just in case.
