One other thing I will say about Marty's Telly and Snuffy is that they're prime examples of what some Muppet Performers have talked about when recast characters tend to start out as being pretty much just straight-up imitations of their predecessors, and that's essentially what him Telly and Snuffy were. It seems like it wasn't until the late 80s that he really started making Telly and Snuffy his own, but if you listen to his performances as both characters in the mid-80s when he took over, they definitely sound like imitations of Brian and Jerry. It's not quite as noticeable with Snuffy other than the cadence, since Jerry's Snuffy had that slow, sad way of talking, which Marty's Snuffy also had in the beginning, but it's definitely noticeable with his Telly in the beginning . . . in fact, watching FTB you can hear how inconsistent his Telly was throughout the movie.
