Depends on what you call cheating. In sport I get pretty hyper-competitive, I have been known to appeal and get decisions in cricket which I shouldn't have (but I'm a wicket-keeper and there's not one out there who wouldn't have at one point in time or another), I've flopped like a b**** in basketball, stuck my knee/elbow out when setting picks or taking charges just to ensure I hold the otherr guy up or contact is made... (I had a local tv new anchor curse me out for a flop I took on his son in a high school game) and I played scrum half in rugby ('nuff said) at times.
Have you ever sent a photo of your dingus?
