Trying to Pull a Realist's Funny Bone

Have you ever try to joke around with a very serious person?   It is a challenge.  If you tell them a joke that starts off with a man and a turtle walk into a bar and the turtle orders the first round of drinks the serious person will interrupt you to  quickly point out that turtles cannot talk like humans and will probably google you information to confirm their statement.   And it  is always like this.

I cannot imagine what happens in their mind when they see Looney Tunes cartoons with talking rabbits, Coyotes buying a case of Acme Dynamite, a cat with a slobbery lisp... wait there is a little guy with a shotgun, he is believable.
