Q: Where do ghosts like to go sailing?
A: Lake Eerie!

Explanation: If you ever get the chance to go sailing, I would highly recommend it.  It is a beautiful experience to let the wind move your boat without using a motor.

Ghosts, of course, like places that are scary or frightening.  The word eerie means strange or frightening.  An eerie experience might be sitting alone in a dark house, hearing strange sounds, and seeing faint lights that look like ghosts.

Lake Erie is the 4th largest of the Great Lakes in North America.  I have never seen it, but the pictures sure look nice.

This joke is funny because it plays with the words eerie and (Lake) Erie which sound exactly the same.
