I had a mate that used to come round occasionally an train with me, one day he was benching when all of a sudden I heard weights dropping all over the place.. I turned around and hes laying on the bench holding just the bar with a stuned look on his face.. all the weights had fallen off and were laying all round him. I said what the hell happened! and in reply he said "I had an itchy nose" ....he had an itchy noes while he was benching and tried to scratch it mid way through a rep.. I was speechless...
