As it happens, it's Danielle's B-Day. And, being that she works here at Best Buy Metal Roofing, that means its also prank day. (Yeah look at some more of my videos and you'll see.)
As it happens, I was on the phone at the time the prank occurred. I continued talking on the phone, explaining venting, condensation, and other roof wonders to the caller, while videoing the entire prank.
