who'd win in a fight, thing one or thing 2???

Went to training as usual for a Friday night.  Coach started to show us some of the applications of the new stuff we were learning.  As usual I was the punch bag/dummy, I don't mind, actually I like it, think it's the best way to learn.  Though tonight was a little different, I actually mamnaged to bring down the coach, that's a first though if I'm honest it was also completely un-intended & actually something I wish had never happened. & here's why:

so the coach is using me to show how this one move works, I punch at him, he grabs me, makes me almost double over coz he''s bending my elbow in the wrong way, then he steps into me & throws me completely off balance same as always.  Next he says, " but when you're really using this, you have to be fast, punch me again mark" so again I throw a blow at him, be blocks with the first hand, then uses his second hand to bring me off balance by lowering my elbow.  but this time he does it that quick that unless he does something I've got an urgent appointment with the floor.  He steps in as I'm heading towards him, on my way to the ground. BANG, he flips me back in the opposite direction from where I've just came only he's never used such speed on me before, sure he's been quick, but not like this, I go arse up, he sees it, tries to stop mebut comes down with me.  I don't mind the cuts & grazes I got from it, there nothing, but the thing that did knock the steam out of my practice for the rest of the night was his knee in particular where it landed.  The coach fell right ontop of me, & he's not a light fella, but his knee was planted, lets just say, somewhere that significantly reduces the chances of my mum becoming a grandma.  I limped home after training!
