Oops! I broke something!

Well, I got my first job (at Chick-Fil-A) a while ago, and it took me about a month before I broke something. You see, I was cleaning up after close, and we were getting ready to go home, when a coworker (who shall remain unnamed) said, "I'm gonna do some pull-ups," pointing to the shelf above the kitchen door, which holds lids (in boxes). I watched as he did about three or four reps, then commented, "That's great, I bet I couldn't even do one." Not to be talked out of my own dare, (because of stupidness, pride, and wanting to show off) I jumped and pulled my self up (one!), then began to repeat, when the screws on the right side of the shelf came out of the wall! Needless to say, I fell, but landed unharmed. We spent the next 15 minutes finding tools and trying to fix it, finally giving up after putting it somewhat back together. The lid boxes are now resting on a cart in the back, and I am pending punishment/payment (I don't really know, but if what I hear about the owner is right, I'm in for something)
