I was once towing a C152 into a hangar on a golf buggy, local rules meant you had to detach from Buggy at hangar entrance as only hand towing permitted inside. As I lifted the towing arm eye off the towbar, the little old 152 rolled forward slightly and my finger was trapped in between the towbar and the back of the buggy...instantly popped my nail straight off. A mistake I have never repeated
