Multi-tasking a little too much

Ah the stories I hear at work...

Co-worker came up to my desk and narrated the following:
She was on her way to the bathroom and came across another co-worker who was apparently having an intense convo on the phone. Little did he realize that while he continued walking, and talking on the phone, he started to unzip his pants before even entering the bathroom. He was apparently 'still 10 feet away from the bathroom door!' claims astonished co-worker.

She didn't want to disclose the name of this guy. Damn corporate ethics!
