William Shatner Joins 'Extra' at The Grove

Legendary actor and star of "$#*! My Dad Says," William Shatner stopped by The Grove to talk with Mario Lopez. Shatner said he calls his show, "Poop My Dad Says." "It's the poop Dad says, so what's wrong with that? It's cool."

Shatner revealed he has been riding horses for a lifetime and competes in reining (a western riding competition for horses where the riders guide the horses through a precise pattern of circles, spins, and stops). He plans to use those skills for charity in a competition on April 30 sponsored by Wells Fargo. "All the proceeds go to help children's charities."

Check out William on "$#*! My Dad Says," airing Wednesdays on CBS.
