To make sure my students pick there feet up on landing,
If your feet touch the ground before mine, we will fall over and I will land on top of you and surf you ( I am 6'6" 270 lbs). Then they have a look of fear.
As I video, I tell the student at the end of the in plane interview, "I am gonna hang on the outside of the plane and wait for you".
I got some really cool double takes for that.
