Well, I once tripped over a carpet in our school, landed on my back with a perfect ninja-like grace, on my hands, without flinching, and just got up.
Everyone laughed, but once they stopped, they just explained it looked cool that a rather big guy like me could pull that off and walk around just fine.
Or even I was intentionally dropping to the front to scare a girl in our class. It was fun, too, and we both got laughs - her for being scared so easily (still is), and me for falling on my front 3-4 times in a row with little to no damage.
...bug my knees hurt a bit, I should've practiced that trick earlier...
