Dancing Duck

[WillyL]

A circus owner walked into a bar to see everyone crowded about a table watching a little show.

On the table was an upside down pot and a duck tap dancing on it. The circus owner was so impressed that he offered to buy the duck from its owner.

After some negotiations, they settled on a figure of $10,000 for the duck and the pot.

Three days later the circus owner runs back to the bar in anger, "Your duck is a rip off! I put him on the pot before a whole audience, and he didn't dance a single step!"

"So?" asked the duck's former owner, "did you remember to light the candle under the pot?"
