Three princes showed up to marry her.
The king announced that the prince who brings forth the most ping pong balls may take her hand.
The three princes take their leave and go on their separate ways.
A week later, the first prince shows up with five horses in a tow, each carrying two huge sacks of ping pong balls.
Next comes the second prince with ten horses in a tow, each horse carrying two huge sacks of ping pong balls.
The king tells the two princes that he needs to wait for the final prince to return.
The king sees the third prince returning with only one horse in a tow with two huge sacks… The king was very upset, and asked the third prince, ‘is my daughter not worthy enough to bring back only two sacks of ping pong balls?’
Prince replied ‘ping pong balls?! I thought you said King Kong’s balls!’
