LOS ANGELES - Kermit the Frog, that Muppet of all Muppets, has got to have other Hollywood stars green with envy.

He's turning 50 years old next month but doesn't look a day over... well, he looks pretty much the same as in the mid-'50s, when he made some of his earliest appearances with puppeteer pal Jim Henson on the local Washington, D.C. TV show, "Sam and Friends."

And Kermit doesn't seem to have aged a day since getting his star-making breaks in the late 1960s, in the telefilm "Hey Cinderella" and on the children's TV series "Sesame Street."
