I would of lost it once the coworker got all red.
As someone mentioned before, it is a deep psychological fear of some men of other mens (doesn't have to be a black guy) large(r) pieces. I really do not understand it . I told my manager how my good friend (white guy) is known for having a pet iguana down there. Everyone at our high school knew it once he jumped off a roof naked into a pool at a party once. I've only seen it accidentally about 3 times, once from about 50 yards away and I thought he was holding a wiffle ball bat between his legs. He notoriously can put an iPhone 4s under it and you can't see the iphone
Ever since, everytime I bring up my friends name my manager gets all strange and pissy. Weirds me out man.
I'm white if it matters.
