Abby Elliott, who’s been given far too little to do on Saturday Night Live this season, made a funny, charming, and dare I say hotsy appearance on The Late Show last night. For Letterman, it was almost a family affair, since Elliott is the daughter of Letterman grad Chris Elliott, who made a funny cameo appearance during Abby’s segment:

You know Chris, right? The Man Under The Stairs? The star of the short-lived cult masterwork Get A Life? The man who did one of the best Jay Leno impersonations ever?:

And of course I don’t need to tell you that Abby’s grandfather is Bob Elliott, half of the great comedy team Bob and Ray. Their low-key, poker-faced routines were the exact opposite of the broader comedy that Chris and Abby do, but no less funny, as on this old Johnny Carson Tonight Show clip (Bob is on the right):

The Elliott clan: a comedy dynasty.

What do you think of Abby, Chris, and Bob?
