On 'Good Morning America' (weekdays, 7AM ET on ABC), six cast members from 'Welcome Back, Kotter' reunited and fondly recalled the seminal sitcom. In particular, John Travolta thanked Gabe Kaplan for giving him a start in acting, and Kaplan revealed the origin of Vinnie Barbarino's catchphrase.

"I've waited thirty-five years to thank this man," Travolta said, gesturing to Kaplan. "I never got to publicly thank Gabe for his genius, his putting us on the map. You know, we all wouldn't be here today without Gabe."

Here on TV Squad we already covered the launch of In2TV, a new service that lets you indulge your nostalgia for old shows via the magic of streaming video. Last night, I got to indulge in a little nostalgia first hand at the In2TV launch party. I am the worst person to send to events like this; I'm a lurker, too shy to talk to anyone and not the best with a camera, but as the only L.A.-based member of TV Squad, it was my honor to check out the scene.

The  event took place at the Museum of Television and Radio in Beverly Hills. Gabe Kaplan took the stage, made a few jokes about the new Welcome Back, Kotter movie and showed off the In2TV concept. He was a good sport and even brought out a paper airplane to put on his head, joking that it didn't stick as well as it used to (aw, Gabe, you're thin on top but we still love you.)  He introduced George Lopez who gave a heartfelt tribute to Freddie Prinze, showing clips of the comic's career and snippets of episodes from Chico and the Man. Somehow, in George's speech, he managed to reference the fact that he has one kidney and his wife gave it to him (is there anyone who hasn't heard this story yet?) He announced the In2TV Influencer Award and handed the strangely shaped trophy to Freddie Prinze Jr. Freddie made a brief speech, then Jose Feliciano was brought to the stage to play the Chico and the Man theme (with just a bit of "Light My Fire" thrown in). The crowd was full of old favorites from the TV days of long ago. After the jump, a few familiar faces.
