Constantly banging my head on the flaps of the 152....
Tripping over the wheel and falling backwards on to my ar*e, then standing up quickly to save face in front of the chuckling people who happened to witness it and then banging my head again on the flaps.
Walked into the stationary propeller cutting my leg
Slipping off the wing strut whilst checking the fuel level.... and to be fair the list goes on....
Sometimes wonder if I am safe to fly being so clumsy....
