In a zoo, a woman sees one of the zookeepers trying to push a Camel into
an enclosure. The camel refuses to move one inch. The woman
says to the (male) zookeeper, "Here, let me help." With that, she goes
behind the camel for a few seconds. Suddenly with a shriek, the camel
gallops away into the distance.
The zoo keeper says, "What did you do?". The woman says, "I tickled his
testicles". The zoo keeper says, "Well, tickle mine, I've got to catch
the bugger now!"
