One of the worst things that can happen to anybody walking into a theater is to know all about the twists and turns and surprises that are in store. If you know, then it's not a surprise. Following my intense belief in not having the shout "spoiler alert" every time I see a play, I fully intend to say almost nothing about what happens in "Any Given Monday," an hilarious if slightly off-kilter comedy that opened over the weekend at In Tandem's Tenth Street Theatre.
