This one is classic!
Back in college, I was living in the dorms and I had just started seeing this new chick. I wanted to tend to my bush as I had not maintained it for a while and I was planning on getting laid that night. Anyway, all I had were scissors (no beard trimmer) so off I go into the bathroom, snipping away to tame the beast and I accidentaly clip a small spot on my nutsack. That fucker was bleeding A LOT and I ended up having to put a big piece of gauze on it and secure it with medical tape.
That evening I was invited to do some powerliftng with my buddy and one of his friends who I had never met before. We do a few warm-up sets and then the guy suggests we jog a few times around the track before we really get down to the heavy stuff. (I don't normally do this, and I thought it was strange, but this guy was huge and strong, so I just went along with it.) Anyway, we start jogging and I'm starting to sweat and just as we are winding down, a bloodied white gauze drops out from the bottom of my shorts. This dude just looks at me with a straight face, looks at the gauze and then looks away. I tried to explain, but he said he didn't care. The entire lift sesion, the akwardness I felt was killing me, I was trying to squeeze in an explanation, but for some reason the guy was just adimant about not wanting to hear it.
I never was invited back to lift with that guy again...but on the brightside I did pull a personal best on deadlifts that night. I believe its because I was trying to compensate for feeling like a douchbag.
