Guy Smiley is, by his own account, America's Favorite Game Show Host. He has hosted the Sesame Street game shows "Beat The Time," "Here is Your Lif,e, "What's My Part?" and many others. He approaches every hosting gig with a near-frantic level of excitement and enthusiasm.
 
Guy Smiley has occasionally demonstrated his musical talent on Sesame Street. His song performances include "Air" and "They Can't Take That Away From Me" (with Cookie Monster). His singing voice at times can go very low, very similar to Link Hogthrob's, as in "I'll Love You in Springtime" and his tribute to the winner in "The Letter of the Day Pageant." He also sang "Gone with the Wind" in the first season.

Most of Guy Smiley's appearances in sketches have been as the host of game shows. Many of the sketches where he doesn't host game shows still involve him being the host of a show, including "The Weather Show," "The Letter of the Day Pageant," and "On Vacation with Guy Smiley." One of the few sketches in which he starred where he didn't host a show or sing was a sketch where he took his entire studio audience out for lunch. His first appearance was in a sketch where he appears as a spokesman for "Brand X." (Episode 0010)

Although Joan Ganz Cooney once described Guy Smiley as one of Jim Henson's funniest characters,[1] he was Henson’s least favorite to perform; as the character’s boisterous voice was too rough on his throat.[2] Because of this, the dialogue for Guy's earlier sketches was commonly prerecorded, so multiple takes could be filmed without straining Henson's throat.

A walk-around version of Guy Smiley appeared in a number of Sesame Street Live shows. In Big Bird Goes Hollywood, he assisted Big Bird in directing a movie. Guy Smiley also appeared in Big Bird's Sesame Street Story and Big Bird and the ABCs
