Father knows best?

On Thursday's Tonight Show With Jay Leno, Ben Affleck explained how he accidentally taught his 3-year-old daughter Violet how to cuss in German.

They were eating at a Mexican restaurant when she accidentally spilled water. Affleck says he almost blurted out the "s-word" but caught himself and ended up yelping, "sheisse," the German version of the word.
