John Stamos is not just playing doctor. As "ER's" new physician, he's quite serious about his white coat and his rep as the resident hunk hovering over a gurney.

"I just did a movie with Eric Dane, but I haven't seen 'Grey's Anatomy,' " Stamos says of the competition on, uh, another network. "I'm the true Doctor McSexy.

"Consider that I've been wet in every episode of 'ER,' " says Stamos, who plays Dr. Tony Gates, a Gulf War veteran with a chip on his shoulder. "I've been called Dr. McStamoist. I think next week, there's a pregnant woman whose water even breaks all over me."

So much for sexy.

I've done a lot of TV that has failed. Oh, yeah, "Full House" was a hit, but when it began, I heard, "This won't last until Thanksgiving." I guess you can say joining an established show is the best job I've ever had.

I don't really like medical things. My mom was in the ER for real a few months ago. My poor mom had burned her house down. I raced to the ER. I didn't look around in the name of research.

My friend Bob Saget is telling people that now I race into Cedars-Sinai hospital in Los Angeles to do operations in my spare time. I switched a heart out last week, and the woman is fine. She looked up happy knowing that Uncle Jesse from "Full House" operated on her.

I tried to do my own show. Then I said, "Wait just a minute. Why don't you go on a show where everybody already watches it?" But I don't think I was mature enough to handle "ER" earlier in my life. It's the right thing to do now. The big joke is they're giving me great writing and a lot of money. And people are watching.

My doc is starting to get into a romance. I'm taking care of my best friend's widow and daughter. It does become sexual at times. At the same time, I'm starting to fall for someone in the ER. The romance will heat up in the next few weeks. 

The best part is everyone is like, "Wow, we didn't know you could act." The truth is I'm an adult now, and I care about my craft. I want to do my best.

I just make the medical jargon up. One of the doctors who teaches us the medical lingo looked at my new car and couldn't pronounce Cadillac Escalade. He wants me to say the most difficult medical terms and he can't say Escalade?

I asked, 'This will get me more chicks?' Just kidding. Actually after my public divorce [from Rebecca Romijn], I've been kind of searching in my life and starting over. I feel that the show puts me in a great place. My life feels full and satisfying. I'm happier than I've ever been.

It's funny that Bob Saget is on NBC doing a game show ['1 vs. 100']. We're single-handedly saving the network. The two idiots from "Full House." It's all on us.
