"How could you not notice he'd replaced me, Fozzie?"
A bit random, but a piece of dialogue I'd always wanted to see in the scene where Walter, Fozzie, and Animal rescue Kermit from the gulag that I thought would've added a bit of tearjerking-ness to the scene (well, more than there already was). It'd take place right after Kermit's big blow up of "Not ONE person from the Muppets except Animal noticed I'd been replaced by an evil criminal mastermind?!"
Kermit: *looks at Fozzie* "...My oldest friend?" *looks at Walter* "...My biggest fan?" *looks down, sadly* "...Piggy?"
