I’ve been to tapings of both *Night Court * and Who’s Line Is It Anyway? There weren’t any laugh or applause signs, but they did have emcees come on to warm up the crowd. The emcee for *Who’s Line * did say that audience reaction was always enthusiastic to the British version of the show, and if we wanted to come second to a bunch of brits, well -
BTW - it was Harry Anderson’s birthday the day of the *Night Court * shoot. Everyone in the audience got cake, Anderson did a little Q&A with us, and John Larroquete saw a cute girl in the fourth row and climbed over the seats to sit next to her. That actually got the biggest laugh of the night.
