Uhhh...I hope that the "Hensen" you are referring to is his son....
Second...Well..considering that The Muppets are once again up for sale (and so far..the highest bidder is Disney), I see nothing wrong with it.
I know that Muppet Treasure Island was years ago...but dont forget that the muppets are actually in Disney parks, and I am sure disney if anything would ENCOURAGE it. I could think of much worse things to be mentioned in.
Dreamworks and other various companies that HATE Disney have taken pot shots at em for years..hell..95% of shrek is aimed at poking fun at Disney.
It is all just more exposure for Disney...
Anyway..back in topic::
Some other references::
Shrek - The obvious Farquad resembelence to Eisner.
Shrek - The fact that Farquad was a midget is reportidly a reference to a time Eisner called Katzenburg a Midget.
Geez....I am having a major brain fart right now (being at work does that to me)...i'll post more later
