I agree with Broadwaytheatre11...use something that is special for you pertaining to high school-inside jokes, quotes of friends or funny things people have said. Stuff you all ahd fun doing. Examples some of my favorite high school quotes:
"Someone has a line here and it's not ME!"-said by everyone involved
@ one point or another-basically sums up mentality of fall play
"People who make lofty moral judgements without sufficient supporting detail are pretentious asses"-said to a teacher by a friend while whole class goes wild cheering
MANY MANY MORE I mean they might not be that funny or insightful to other people out of context but I read them and they make me laugh really hard and remeber moments..if ou think a quote from a show can do that for you then go ahead
"I guess she is one very confident girl who feels if you see it, it shall be.
I hope she sees a room with a piano player and a bunch of scary middle-aged queens sitting behind a table, talking to each other as she auditions!!"
