I seen this crazy biker guy who does bench comps or whatever he does come's to the gym ever night in biker gear takes jacket off and benches for about 30 minutes strong as an ox anyways a trainer was kicking all the swiss balls to the corner cleaning up the gym area one hit him while on the bench and son of a bitch racked it pulled out is switch blade slashed every ball in the gym, put his jacket on and rolled the gym havent seen him since but at least he got rid of all the balls for the rest of us
