It's been nearly 10 years since Everybody Loves Raymond went off the air, but creator Phil Rosenthal still remembers the moment he knew he had a hit on his hands.

"They would bring in audiences from prisons and nursing homes [and] they laughed for over 30 seconds, which is a big laugh for people who don't know the characters," he told TVGuide.com at a recent cast reunion. "That's when you know maybe you have something."
