Guy Smiley was a character on Sesame Street who was dubbed "Everybody's Favorite Game Show Host." This nattily attired character is easily excitable and is perpetually shouting, and resembles host Jim Perry. Apparently Guy Smiley is not his real name - in one Sesame Street skit, he stated: "Well, my name's Guy Smiley, and they call me that because I changed it from Bernie Liederkrantz!"

Guy Smiley has hosted many of the following game show skits, such as:

• The Remembering Game — A spoof of Concentration, two contestants try to match prizes on a four-space board. In its one appearance, Cookie Monster and an Anything Muppet named Bill Smith didn't like the prizes they had "won," so they traded prizes. Cookie had won an airplane and Bill had won a cookie.

• What's My Part? — A spoof of What's My Line? — Three blindfolded celebrities had to identify a body part before all three of them were disqualified (by asking a question that had a "no" answer). The first segment, featuring a nose, starred panelists Cookie Monster, Bennett Snerf and Arlene Frantic (the latter two Muppet parodies of longtime What's My Line? panelists Bennett Cerf and Arlene Francis). It ran for 4 segments.

• Mystery Guest — A spoof of a term used on What's My Line? — The contestants, (Cookie Monster, Don Music,and Sherlock Hemlock), must guess who the Mystery Guest is. In this clip, it was the letter X, but nobody guessed correctly, and it turned out that the letter X belonged in the exit sign. It ran once.

• Beat the Time — A spoof of Beat the Clock — The contestant must bring in a number of things that rhyme with the key word or contain something. In the most famous segment, Cookie Monster must find three things that rhyme with "rain", and will win a cookie if successful before the arrow on the clock reaches zero. Cookie manages to find a cane he stole from an old man, a chain holding a monster (Frazzle) and, at the last second, arrives onto the stage by smashing through the wall with a train (the same train he rode in "The Ballad of Casey McPhee"). It ran for 5 segments. Another "Beat the Time" involved the Count, where the Count has to bring in two things that come from the sky (his thunder and lightning when he counts). This is the one where Guy reveals his real name to be Bernie Liederkrantz.

• To Tell a Face — A spoof of To Tell the Truth — A Baby must figure out who is real person out of three panelists. It ran for 7 segments.

• The Triangle is Right — A spoof on the title The Price is Right — Every question is answered with the response, "A triangle." It was short lived.

Guy has also hosted parodies of This is Your Life called "Here Is Your Life." Guests who were profiled included a loaf of bread, a tooth and a tree (all aimed at teaching children how things are made). He has also hosted pageants for numbers and letters.

Performed by Jim Henson, the character was mostly discontinued upon Henson's death in 1990. He appeared as a background character in a street scene in 1998, and was performed by Steve Whitmire. He also appeared in the CD-ROMs, "Let's Make a Word" (a spoof of Let's Make a Deal) and "Get Set to Learn", where his voice was credited to Don Reardon. More recently the character has been played by Eric Jacobson, starting with video inserts in the touring exhibit "Sesame Street Presents: The Body".
