I personally have probably struck my electronics over 100 times.  But there are a few incidences that stand out from the bunch.  About two years ago I was playing Halo: 3 with one of my friends, when all of a sudden my Xbox got the red ring of death and shut down.  I sat down to restart my Xbox but the power button just turned red again , I did not bother turning it off I just punched it, lo and behold the power button turned green again and i was back to playing Halo.  So far I've had the the red ring of death five or six times now and they have all been solved with punching.  Something similar happened recently, but not with my Xbox, but with my Ipod.  One day I was brushing my teeth & holding my Ipod at the same time (NOT SMART), when i accidentally dropped it into the sink filled with water, at first I said to myself "whatever it won't do any harm" but then when i tried to play some music...... NO SOUND.  I tried to figure out what was wrong but I ended up just throwing the thing at the nearest wall, problem solved, the sound works again :).   Another time I was just sitting on my little red cube playing some computer games, when all of a sudden the screen fades to black, then I thought to myself "If only life was this easy", Punched my laptop, the screen flared to life, and I'm like "YES, just YES".
