Maddox Jolie-Pitt has a license to drive... a boat?

The 8-year-old took the wheel of a water taxi in Venice, Italy, Thursday afternoon. Little bro, Pax, 5, and an adult male served as passengers. (Not present: Angelina Jolie or Brad Pitt!)

Jolie has been filming The Tourist in Venice, while the rest of her brood has spent most of their time eating gelato and sightseeing.

Maddox seems to be a little risk taker. Indeed, his mom already bought him a knife!

"My mom took me to buy my first daggers when I was 11 or 12. And I've already bought Maddox some things. We take him to a special shop," Jolie told the November 2008 issue of W magazine. "We also talk about samurais and about the idea of defending someone as good. We talk about everything."

His younger sibs are also into weapons.

Last month, Shiloh, 3, sported a toy gun holster (and skull cap!) while out and about in Venice.
