You know you're a thespian when:

You are watching Glee’s West Side Story scene and you say:

"That blackout was 45 seconds. What the hell? Cut that down to five and you’re good. AND that was on a show night."

oh and

"Why are the house lights on?"

and

"Why are there lights backstage instead of clip lights?"

I love Glee but, RIB, get your theatre stuff right.
