When Rachael crashed the set of ER, she got to meet the newest resident on the block, John Stamos. The hot doc definitely brings some heat to Chicago's County General, but when John comes to Rachael's kitchen to make Greek Fire Cheese, the flames are really cookin'! Watch the video above to see the heat!

Some people might be surprised to learn that John once played drums for the Beach Boys on tour. Does he still hang out with them? "I just did New Year's Eve with the Beach Boys in Vegas," John says. "It was great. I have had them on every show from Full House and You Again? and these other shows that I've had. And then they said they wanted to be on ER. I said, 'You're going to have to play cadavers!'"

In honor of John's Greek heritage, Rachael makes "Stamos" Gyro Burgers with a Greek Salad. Surely John, whose original family name was Stamotopoulos, can settle the debate over how to pronounce gyro, right?

John admits, "I say, 'Just give me that Greek sandwich!'"
