This and that: "Family Guy's" 100th, "ER's" 300th

It may have taken them a little longer to get there than most shows, but Fox's unsinkable "Family Guy" is prepping a 100th episode party for Oct. 29 at the ever-fashionable Social Hollywood. Seth MacFarlane and his crew are known to know how to celebrate their "freakin' sweet" milestones. This bash might lend itself to some TMZ moments, if Stewie gets out of hand...

There might be some TMZ action coming out of next week's Hollywood Radio and Television Society gathering of the heads of the five network families. The selection of Barry Sonnenfeld, helmer and exec producer of ABC's "Pushing Daisies," as moderator of the Oct. 16 luncheon has raised some eyebrows among rival nets. It's a head-scratcher for others, given that Sonnenfeld isn't exactly known for his emcee-ing skills. But for those of us who've complained about milquetoast HRTS moderators in the past, we've got to give Barry the benefit of the doubt. It outta be a lively sesh, anyway, with ABC's Steve McPherson, CBS' Nina Tassler, CW's Dawn Ostroff, Fox's Kevin Reilly and NBC's Ben Silverman...

The milestone-episode parties continue on Nov. 3 with Warner Bros. Television's celebration of "ER's" 300th at Hollywood's Cabana Club. Hard to believe it was 13 years ago that George Clooney did such an effective job of playing the tipsy Dr. Doug Ross in the famously good two-hour "ER" pilot. NBC skein has had its ups and downs since then but it has earned its place in the pantheon of primetime's longest-running series, and casting history. This party outta be a classy affair to remember, especially if it attracts a full (or even pretty full) complement of thesp, writer and producer alums....

And from the good-cause department, Zimmer Children's Museum will fete Fox talent relations exec Missy Halperin (pictured left) and PBS' kidvid programming exec Linda Simensky (pictured right) at its 7th annual Discovery Award dinner on Nov. 8 at Regent Beverly Wilshire hotel. Brad Garrett and Joely Fisher, the battling spouses of Fox sitcom "'Til Death" will emcee. Zimmer org is focused on teaching small fry about ethics, community involvement and cultural sensivity through interactive and roll-up-your-sleeves exhibits at its museum on the Miracle Mile.
