I like to hacksaw bits of my wheel, a little bit at a time. I know I've gone to far when I can't turn at the end of the straight. Whilst I'm flying over the gravel trap I like to attempt to wedge the offending (lack of) piece back into place, so I can scoot round the edge and rejoin the track.
All with losing a position.

Or, I like to see if I can swap my feet on the pedals (so my left is on the accelerator and the right on the brake), without lifting or braking. At the same time I cross my arms over. At this point I shout 'take the photo' at the assembled crowd, pose, wave, sign some autographs, revert to standard pedal/wheel positions, and finish the overtaking move.
But it's only entertaining in the Sauber.
