Maybe not to that extent, but say like older Super Grover inserts: he arrives (crashes, more like it) at the scene of whoever is distressed . . . and they're actually disappointed he arrived.
LITTLE BOY: Look! Up in the sky! It's a bird! It's a plane! It's. . . .
SUPER GROVER: (Crashes) It's Super Grover.
LITTLE BOY: Oh rats!
I mean, even Frank has pointed this out: all Grover wants to do is be helpful to the point that certain contractions like "can't" and "won't" aren't even in his vocabulary.
It's hard for me to think of either Kermit or Mr. Johnson being considered Butt Monkeys, because they have tendancies to lose their patience with others, and in a way, kind of invite misfortune on themselves. Grover, on the other hand, is persistent and determined to help others, even if he doesn't know when to stop, so whatever misfortune he invites on himself is more pitiful.
