Short joke: How do you make a tissue dance? You put a little boogie in it!
Long joke (In honor of my grandpa, rest in peace. He told me this. Not well, but he told it.): There was a brother and sister living in Ireland. The sister comes to the brother's house crying, and he, being a caring brother, asks her what's wrong. She says that her fiance, James Dunn, ran off on her to go see some other woman living in America.
Furious, the brother gets a plane ticket, and he goes right to America. How dare this man make his sister cry! He cows he's gonna fix this, mark his words!
Well, he gets to America, and he starts... wandering around, having no real insight as to anything about this Dunn person. He's still full of righteous rage, however! He wanders into a bar, slamming the door along the way, and he yells at the barkeep "I'm looking for James Dunn!"
The barkeep stares at him with a raised brow, before pointing to the bathroom.
The brother storms into the bathroom, and sees that indeed, there's a set of feet poking out in a stall.
He slams his fist on the closed door a few times, before yelling "ARE YOU DUNN?"
The man inside (Not wanting to cause a fight with this random stranger yelling at him in the toilet) quietly goes "Y-yes?"
The brother says "THEN WHY DON'T YOU COME HOME AND MARRY MY SISTER?"
