On that list, I’d say the tarantula, being the only invertebrate.
Although the python can also be argued, as the only one without legs or ‘fur’.
As for a new list…
(Kind of a softball, sure…)
Batman, seeing as he’s the only detective that insists on wearing a mask.
Not so easy:
Ah, now you see the twist–guessing the off-the-wall/arcane category the previous poster has dreamed up.
For example: “animals you might find in a pet store”
You go to the wrong pet stores. In’t that right, Logan? ‘Rrrrr!’
Tyger - quite true, actually, though the difference I was going for was actually rather more…intrinsic, making the answer a different one. (Funny, it seemed like a softball when I was making the list…)
That is easy. Superman is the only one who doesn’t wear a mask. Specifically a domino mask, even.
WAG but Robin - because he’s the only sidekick.
Or it could be Speedy, because altho the others may have “endorsed” commercial products, Speedy (AlkaSeltzer) was created specifically to endorse a product
A Chorus Line
Allan Pinkerton is a real person.
A Chorus Line’s choreographer was Michael Bennett. Bob Fosse did that duty on the other three musicals.
Yep, that’s the one I was going for.
You see, that’s the problem with these things. It’s easy to find things that don’t belong.
Batman – wears a mask
Sherlock Holmes – only one that is English. The only one who plays the violin.
Sam Spade – only character to appear in a single novel.
Allan Pinkerton – only one who wasn’t fictional.
Hercule Poirot – the only one to have a moustache (and not a beard).
Chicago – only one not to win a Tony in its original run.
Pajama Game – only one to win Tonys for best musical and for best revival
A Chorus Line – Fosse.
Damn Yankees – Only one whose original lead actress reprised her role in the film version.
Right. I was gonna do Batman, but I decided to be a bit nicer.
And you’re all lucky I didn’t make this a Thundercats question.
The only one that is not an Apple operating system?
Heh, I guess it’s too prosaic to say that the tiger is the only one without spots.
I was going to say Superman because he’s the only hero identity still being performed by his original “secret” identity. But I was thinking Green Lantern not Green Arrow.
The Cheetah is the only one who does not climb trees?
The National Football League
The National League of Professional Baseball Clubs
The National Hockey League
The National Basketball Association
(and no, it’s not that one is called an association.)
Willie Mays-Only one living
France-Doesn’t end in A(ok,I know that aint it)
Well China is the only one not a Democracy, but France is the only one that was never part of the British Empire, if you count Hong Kong as part of China.
