A zoo joke I had never heard before:

A man built a zoo..
He made the entrance fee $60 but no one enters his zoo.. He reduced it to $40 but still no one came.He made $10 for the entrance but no one still enters..

What the man did, because no one was coming in even though the entrance fee was very low, he just made it FREE.

As a result, many people entered the zoo and it was filled with people. More than 4000 people came in.

He then quietly locked the zoo gate, freed the crocodiles, lions and tigers and then made an exit fee of $100.Everyone paid immediately just to get out!
