[font=arial, helvetica] 95.) HELP! We must know! Is Miss Piggy's last name "Piggy?" Does she have a last name?
[/font][/font] [font=Arial, Helvetica, sans-serif]
Thank you for your recent query regarding Miss Piggy's name. It is a bit of a trick question. When the idea for Miss Piggy was originally conceived in the early 1970s, the puppet was called "Miss Piggy Lee" - something of a parody of the singer Peggy Lee. Almost immediately, the "Lee" part of the name was dropped, and by the first season of The Muppet Show in 1976, she was known as Miss Piggy. So, no, Miss Piggy does NOT have a family (or last) name.[/font]
