2. To play volleyball. The 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 PM to 7 PM 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.
