Continuity mistake: The gang from the radio station is at Frasier's rehearsing for the radio play - Gil is sitting to the right of Marty's little table - he leans towards the table and puts his hand around a bottle of water but in the next shot he is pulling back from the table with a pencil in his hand, not the water. At the same time Bulldog, next to him, while Gil is reaching for his water, is holding his own water in front of him. When Gil pulls back with the pencil, Bulldog's arm is pulling his arm back from the left too.

As Marty says "we were a simple people", Frasier manages to open his briefcase, take out the script, put it on the table, and put his briefcase back on the floor and be sitting still - all in about 3 seconds. This just wouldn't be possible in real time.
