I get icky when people refer to the characters as 'Puppets' or 'Guys In Suits'. It's the same feeling as if someone told me that Elvis will play Batman in the next movie. There is a fundamental factual flaw in the statement that makes the entire thing ridiculous.
This is also why I loathe the guts of that bitchy middle-aged actress currently selling slimming yogurt on UK TV adverts - she said as much about Kermit and Miss Piggy on the radio, in the middle of the day when hundreds of kids would be listening. Vicious, vicious bitch. She deserves to be selling yogurt.
