   now-demolished {D. C. Power Lab} building used by the Stanford
   AI Lab in the 1970s had a volleyball court on the front lawn.  From
   5 P.M. to 7 P.M. was the scheduled maintenance time for the
   computer, so every afternoon at 5 would come over the intercom the
   cry "Now hear this bounce, bounce!", followed by Brian McCune
   loudly bouncing a volleyball on the floor outside the offices of
   known volleyballers.  3. To engage in sexual intercourse; prob.
   from the expression `bouncing the mattress', but influenced by

   reboot a system in order to clear up a transient problem.  Reported
