During a panel break at TCA today, CBS aired a video with David Letterman, who introduced a special TCA edition of the Late Show Top 10 featuring a list of “little-known songs about television” (aka covers of popular songs with changed lyrics), performed by crooner Josh Groban. Unfortunately, because of music rights issues, a video will not be available, but here is the list (feel free to hum along). My favorite, soug to the tune of I’ll Be Seeing You: “Why do the terrorists hate us so? The answer’s plain to see/ Try to watch 30 seconds of Real Housewives of NYC.” Here is the full Top 10:

10.       Somewhere over the rainbow, way up high
There’s a place that has not been home to a “CSI”
(Sung to the tune of “Somewhere”)

9.         I see Keith Olbermann rant on Current TV, attacking Glenn Beck and Sean Hannity
And I think to myself…what an enormous head
(Sung to the tune of “What a Wonderful World”)

8.         What is the deal with my Tivo
It recommends odd programs to see
I only watch “Glee” and “Project Runway” but Tivo says “Swamp People’s” right for me
(Sung to the tune of “Wind Beneath My Wings”)

7.         I’ve got nine hundred channels comin’ into my TV
And I’d estimate two-thirds of them are selling costume jewelry
(Sung to the tune of “God Bless the USA”)

6.         Check out “Big Brother”
Stay for the hour
And if you’re lucky, you might see someone shower
(Sung to the tune of “Climb Ev’ry Mountain”)

5.         Whenever I watch “Two and a Half Men” I ask myself just what they mean
How’s the kid still a “half man”?  He’s 19
(sung to the tune of “Let It Be”)

4.         “NCIS” Who the hell knows what that stands for?
(Sung to the tune of “You Raise Me Up”)

3.         Why do the terrorists hate us so?  The answer’s plain to see
Try to watch 30 seconds of “Real Housewives of NYC”
(Sung to the tune of “I’ll Be Seeing You”)

2.         Before you critics craft your reviews and dole out your 1-to-5 stars
We here at the CBS Network, invite you to our open bars
(Sung to the tune of “Impossible Dream”)

1.         Those Cialis and Viagra and Levitra ads you see pay for your favorite shows
All hail E.D.!
(Sung to the tune of “God Bless America”)
