From the 60 Minutes archive: The Muppet Show

The Muppet Show's Kermit the Frog told Morley Safer back in 1979 that there was no relationship between him and Miss Piggy "except what you see on television." But that may change when the pair reunites-- at the Smithsonian.

This week, some 20 props and puppets from The Muppet Show cast were donated to the National Museum of American History by Jim Henson's family on the 77th birthday of the late puppeteer.

Watch a clip from Safer's 1979 story, above, to see the ever-flirtatious Miss Piggy tease our veteran correspondent.
