The early Blue Man Group [0] shows off-Broadway (before they were the Intel guys) were billed as "Blue Man/Tubes"
They'd run corrugated pipe from each seat in the theater to the waiting hall.
Which meant that while you were waiting for the next show, you could talk to someone who was watching the current show.
Was pretty neat.
PS: Also walked out of the show with a nice black eye, after my pre-teen self went down in the final toilet paper wave and caught the heel of the guy in front of me. Still worth it!
