Now, we all know that Eric Jacobson has pretty much taken over all of Frank Oz's characters, aside from a few segments a year. The only character of Frank's that Eric hasn't taken over is Cookie Monster--now played fabulously by David Rudman. However, I think that Eric was originally supposed to take over Cookie Monster. Just listen closely to Cookie in the Sesame Home Video intro at the beginning of this video: That sounds an awful lot like Eric. And, it makes sense chronologically. Eric began doing Bert and Grover around 1998. That's around the time that this intro replaced the old one. Frank was probably busy, as he usually is, so they got Eric to do Cookie Monster. After all, David Rudman didn't start doing Cookie until a few years later. Just sort of interesting, in my opinion.
