Last night was the 100th episode of The Tonight Show since Conan O'Brien took over (time flies, etc). His dad sent him a very special video message from his home in Massachusetts, and it's actually weird and funny.

So what does it mean to hit 100 episodes? Well, it usually means the chances for syndication are a lot better. But you also get to eat cake! Here's some behind the scenes video of the cast of The Office enjoying their 100th episode party, with an introduction from Steve Carell. The 100th episode airs May 14.

Family Guy reaches a milestone on November 4th: 100 episodes. To celebrate, the animated series is having a special 'Best Of' episode. I'm hoping it will include moments from the first run of Family Guy, before it was canceled and then resurrected.

The actual 100th episode is about Stewie's quest to actually kill Lois when she and Peter leave him behind to go on a cruise. It airs at its normal time slot, 9 pm. The retrospective special airs at 8:30 pm on FOX on November 4th. That means it's replacing King of the Hill for one night.

Hmmm... best moments of Family Guy? Pretty much anything with Stewie gets my vote. What are your favorite moments?

The third successful spin-off of the original Law and Order series is about to reach its 100th episode, a milestone for any television show. This Sunday's all-new Criminal Intent features the original cast members, Vincent D'Onofrio and Kathryn Erbe, who have been alternating episodes with new detectives Chris Noth and Annabella Sciorra. The episode is called Slither and it was written by executive producer Rene Balcer. The episode is about a European gang leader who likes to kill tourists. By the way, I think the word 'slither' is meant to be a description of the main criminal because the show description doesn't mention anything about snakes. The episode also features Olivia D'Abo, a character whom viewers voted to keep alive during a poll in the show's fourth season. Criminal Intent airs Sundays at 9 pm on NBC.
