As I've said before, Marty really made both Snuffy and Telly his own. Sure, in the beginning, you could tell he was trying to be as close to Jerry's Snuffy and Brian's Telly as best he could (FTB is an example of that), but Marty gave both characters dimension and depth that was lacking during their original incarnations. Even as far back as the 90s - you wouldn't see Snuffy dancing and singing a song like "Bubble on My Snuffle" back in the 70s or 80s. And, my gosh, look at the range of emotion Telly has: he was always a worry-wart, but Marty's Telly can get so caught up in his emotions, he can be almost manic at times, whereas Brian's Telly was more of an Eeyore. As much as I really like Brian as a performer (really, he was one of the more versatile performers back then, it's a shame he left), I really don't like his Telly.
