Ryan Phillippe says his biggest turn off is crude women.

The 'MacGruber' star - whose exes include Abbie Cornish and former spouse Reese Witherspoon - likes women who can make him laugh, as long as they keep their jokes clean.

He said: "If a woman is funny, that will leave an impression and stay on my brain. A girl should do something, anything, to make me laugh. I like dark, intellectual wit. But no jokes about bodily functions. That's not a turn-on for me."

Ryan also revealed he uses his kids as an excuse to get out of bad dates.

The 35-year-old actor - who has two children, daughter Ava, 10, and six-year-old son Deacon, with Reese - added to Women's Health magazine: "On a date if you're not laughing and mentally stimulating the other person, there's nowhere to go. Although you can resuscitate it by drinking. I always have the perfect excuse, 'I have to put the kids to bed.' "
