Listen to This Awesome Hilarious Voicemail of an Accident–Is It Fake or Real?

I ran across this video today, and I thought I should share it. Some guy was supposidly leaving a voicemail for his boss, then an accident happens in front of him. He gives play by play as 4 old ladies get out a beat the crap out of him.

I thought it was funny, but mostly because of his laugh. It sounded very fake to me, but a lot of people in the office think it is real?

What do you think?
