It'd have to be the time I tried to ride a motorcycle.
I asked my cousin (who knew how to ride a motorcycle) to teach me how because my mom won't. So we both got on and I'm on the front, she tells me how to do it and whatnot. When I twisted the handle, I accidently twisted it too far and it went NYOooom- my cousin was like "THE BRAKES, HURRRRYYY."......
