The ping-pong lemma was a key tool used by Jacques Tits in his 1972 paper [2] containing the proof of a famous result now known as the Tits alternative. The result states that a finitely generated linear group is either virtually solvable or contains a free subgroup of rank two.
In routing, a Ping-Pong scheme is a simple algorithm for distributing data packets across two paths.If you had two paths A and B, then the algorithm would randomly start with one of the paths and then switch back and forth between the two.
While the character did engage in serious conversation, Mr. Moose's ultimate goal was always to maneuver Captain Kangaroo into participating in a riddle or knock-knock joke, the punchline of which would inevitably be followed by hundreds of ping pong balls raining harmlessly but annoyingly down on the Captain.

The receiver also wears a set of headphones through which white or pink noise (static) is played. The receiver is in this state of mild sensory deprivation for half an hour.
A graph that shows the number of balls in and out of the vase for the first ten iterations of the problem. The Ross–Littlewood paradox (also known as the balls and vase problem or the ping pong ball problem) is a hypothetical problem in abstract mathematics and logic designed to illustrate the paradoxical, or at least non-intuitive, nature of infinity.
The production company set up chess boards, card tables, and ping pong tables along the Court Street platform for cast and crew recreation between set-ups. Robert Shaw apparently beat all comers in ping pong. [11] Although this was an abandoned spur of track, passing A, E and GG trains rumbled through adjacent tracks on their regular schedules ...
