His son was an escape artist, like Houdini. He had two gentlemen from the audience fasten him in the straight jacket and then wrap him in 40 pounds of chains.
His father timed his escape, trying to do it in three minutes. He worked hard at getting the chains off and out of the straight jacket, but it took him a little longer then three minutes. Still amazing, and looked painful to me.
It was a fun musical, and yes they showed it all, but darn with the placement of their hat and then bright lights we didn't get a peak.
