Things you have done to get out of PE. Watch
I've had my mum write numerous letters about various ailments and stuff like needing to leave early to get to my extra-curricular stuff.
In sixth form we had PE last couple of hours in the afternoon, so I just used to bugger off after my last lesson and get one of my mates to say I'd gone home ill Funny how you stop giving a toss about believability of excuses!
I also had certain teachers who'd get me out of PE by saying they needed my help with something/needed to speak to me/I had to practise for a concert
