Claude the hypnotist explained: "I'm here to put you into a trance; I intend to hypnotise each and every member of the audience."
The excitement was almost electric as Claude withdrew a beautiful antique pocket watch from his coat.
"I want you each to keep your eye on this antique watch. It's a very special watch. It's been in my family for six generations."
He began to swing the watch gently back and forth while quietly chanting, "Watch the watch, watch the watch, watch the watch..."
The crowd became mesmerised as the watch swayed back and forth, light gleaming off its polished surface. Hundreds of pairs of eyes followed the swaying watch, until suddenly the chain broke. It slipped from the hypnotist's fingers and fell to the floor, breaking into a hundred pieces.
"SHIT!" said the Hypnotist.
It took three days to clean up the Senior Citizens Centre and Claude was never invited back to entertain.
