We've all heard the saying "momma's baby, daddy's maybe." But every now and then, you see a father and son that make you say, "Oh no, he's DEFINITELY the dad!"

For instance, have you seen Arnold Schwarzenegger's "love child," Joseph Baena?

This whole video is hilarious! I love TMZ! They always say exactly what everybody is thinking.

Then, there are other celebrity fathers whose sons look like them such as Mario and Melvin Van Peebles, Will Smith and his sons, Damon Wayans and Damon Wayans, Jr., Kirk and Michael Douglas, and Martin and Charlie Sheen.  Can you think of any father-son duos, celebrity or local, where you can imagine the mother standing at Maury's split screen saying, "Look at them, Maury! They have the same EVERYTHING!"
