It's an old joke, but this sketch has been hanging around my folder for a little while.
Just in case you've never heard this monumental Dad Joke:
"How do you shoot a Blue Elephant?"
"With a Blue Elephant Gun."
"How do you shoot a Pink Elephant?"
"Hold its nose until it turns blue, then shoot it with a Blue Elephant Gun."
