Itself

What do you get when you cross a turkey with a banjo? A turkey that can pluck itself!
“The secret source of humor itself is not joy, but sorrow. There is no humor in heaven.”
Mark Twain
What do you get when you crossbreed a turkey with a harp?

A bird who can pluck itself.
Why is the moon so conceited at times?
It becomes full of itself.
Just because your football team calls itself the unicorns doesn’t mean they can play in the corn field.
Good science always checks itself before it wrecks itself.
What does a pizza say when it introduces itself to you?
Slice to meet you.
