Bookmark this one. The Sesame Street Encyclopedia is a detailed catalogue of every character that ever appeared on the children's show and it's guaranteed to set off little bells in the back of your mind. For example, when was the last time you hear the name Guy Smiley? He was the gameshow host who did "Here Is Your Life." Some other names that gave me the nostalgia shivers where Placido Flamingo, Prairie Dawn (who always reminded me of you, Caro), Forgetful Jones and Sully. My personal favorites? The Yip Yip Martians, of course. If any of those names made you go "oh yeah...!" then you'll appreciate The Sesame Street Encyclopedia.
