too true to be funny?

I saw "Four Old Broads" at Arena Dinner Theater this evening,  It is the story of sinister happenings in the Magnolia Place Assisted Living Community and the four old ladies (and one old man - a retired Elvis impersonator) who figure out what's going on, a la "Charlie's Angels" and capture the wicked villain.  I can't remember laughing more at any play.  The actors were excellent, the lines were funny, and the visual gags were very well done.  I would say you must see this play but. sadly, all future performances are sold out.  The scary part is I could really identify with these old broads, well, except for the tap dancing.
