That's not true. The Two-Headed Monster, Sonny friendly (a minor character who I'm surprised was recast) and Gladys The Cow were all recast. Sure, Gladys wasn't recast untill 2003, I've read that the to-headed monster wasn't recast untill 1997, and I don't know when Sonny friendly was recast, but they were. I have also read that Osvaldo was recast, but I don't know if that was before or after Richard Hunt died. Sully was also occassionally used after Richard Hunts death. I don't know who performed him or if Sully even had a regular replacement performer (Sully never spoke, so anybody could have performed him, although even though he didn't talk, Sully still didn't make too many appearances). Also, Forgetful Jones often appeared in non-speaking roles after Richard Hunts death (in Sesame Streets 25th Birthday: A Musical Celebration, Elmo Saves Christmas, and Elmopalooza), and Gladys was occassionally used in non-speaking parts before she was recast.
