Herbert Birdsfoot

Herbert Birdsfoot was introduced on Sesame Street in Season 2 as a lecturer, usually with Grover as his assistant. He served as the replacement for Kermit the Frog's lecturing job during his absense from the show in its second season. With Kermit's return, the character was quietly phased out within a few years, but continued to appear in re-used segments through Season 28.
