Heartfelt tributes to Carlin's comedic genius fill the posthumous ceremony, taped in November at Washington's Kennedy Center, featuring the likes of Jon Stewart, Bill Maher, Lewis Black, Margaret Cho, previous Twain recipient Lily Tomlin, and many others.

But it wasn't just Carlin's sense of humor and his jazz-like facility for verbal rhythms that made him a great stand-up. After coming to fame in the '60s with fairly benign routines (Al Sleet, the hippy-dippy weatherman), Carlin turned in the '70s to sharper cultural observations, ushering in a new era of topical comedy -- not hard-edged like earlier practioner Mort Sahl, but genially, slyly trenchant. And even more broadly effective. (Consider his baseball/football comparison with its cultural take on idyllic/aggressive.)

Carlin also delivered the small-things scrutiny that many folks attribute to Jerry Seinfeld, most memorably in his routines about "stuff."

The Twain special pays honor to all of Carlin's four decades of genius. But it's even better to hear it yourself. Carlin's official site offers a smattering of streaming audio/video (including the "seven dirty words"). And MPI has released the DVD trove George Carlin: All My Stuff, collecting his 30 years of HBO stand-up specials (save his 2008 finale It's Bad for Ya) on 14 discs to explore at your leisure.

This is great "stuff."
