This is Leslie's mother's joke:
An eagle goes looking for a mate.....
He swoops down and picks up a loon.
"I'm a loon, I'm a loon, I love to spoon."
The eagle realizes this will not work, so he kicks the loon out and finds a hawk.
"I'm a hawk, I'm a hawk, I just want to talk."
Realizing that that will not work, he kicks out the hawk and finds a dove.
"I'm a dove, I'm a dove, I don't make love."
Frustrated now at three failed attempts, the eagle kicks out the dove and picks up a duck.
"I'm a drake, I'm a drake, you made a mistake!"
