Tickling coming up on Letterman in Feb

I was watching CBS last night and a commercial came on for the Letterman show. It mentioned about a dozen or so people that were gonna be on in February. As they said their names, it showed a brief scene with each. The very last person they said was Cher. The 2 second scene showed Dave with a hand on her knee-squeezing it- and with his other hand he was poking her in the ribs. WOW! AND SHE WAS LAUGHING. Be on the lookout for this commercial. That was the first time I had seen it, so that is all the info I have. But I wonder- could that have been from an older apperance, or do they actually tape these shows a month earlier than they show them on TV

i don't know

...but I sure hope it's the latter! Thanx for the alert!

i think i've seen that before, i think it's an old clip they just still use for the promo =(. wish there was some new ones.
