Many of the Muppet characters were inspired by real people or other fictional characters. Some Muppets changed over time as they became viewer favorites. Read the stories behind ten of them at mental_floss. Link

I like Pepe the prawn. He's not on the list, though.

I'm a Grover gal myself, though Kermit was always a favorite as well. I had a great Kermit doll as a kid. He was huge, and cuddly and my sister got a hold of him and pooped on him. She was only a toddler at the time, but I still bring it up.
