Ballet thieves

Bill and Benny are art thieves.
They steal art.
But not the art that other art thieves steal.
Like paintings or statues.
These guys steal ballets.
How do you steal a ballet?
I don’t know, but they do.
And there’s nothing more boring than a bunch of anorexic chicks in tights, tutus, and slippers just standing around.
Waiting for the police to find their production of Swan Lake.
Bill and Benny are smart.
They don’t use Craigslist or fences to get cash for the ballet.
They also respect the art of dance.
Just pay the ransom, and nobody gets hurt.
