My son is an Elmo addict. He has Elmo clothes, Elmo books, and Elmo toys. He insists on listening to an Elmo CD whenever he rides in my car and watches the furry Muppet almost every day on "Sesame Street." Oh yeah, he calls his binky Elmo.

And you know what? This doesn't bother me.

Sesame Street, which has been on the air for about 40 years, is still a quality show. It teaches kids the alphabet, how to count and other important lessons in an entertaining manner. The show has some aspects of Saturday Night Live to it with clever bits like having Oscar the Grouch host something called the "Grouch News Network," which featured CNN's Anderson Cooper.

I realize that his Elmo fascination won't last. My son recently discovered Mickey Mouse on one of Walt Disney Co.'s (NYSE: DIS) cable channels. Eventually, Mickey will give way to Dora the Explorer and SpongeBob SquarePants on Viacom Inc.'s (NYSE: VIA) Nickelodeon.
