I'm not Superman but another person...
Don't know about the monk riddle, but I'm going to assume you've got a population of monks, sworn to an oath of silence and lacking material possessions like mirrors, all trying to tell whether they have spots on their face by observing the other monks.
If it works the same way as the blue eyed people on the island, they know that at least one monk has spots, and then gather each evening to see whether anyone's worked it out or not.
If there is only one monk with spots, the reasoning goes like this: "I know there's at least one monk with spots, but I don't see anyone with spots, oh gods, it must be me" - figured out on the first night
If there are two monks with spots, each of them independently think "Huh, I can only see one monk with spots, and if he was the only one he'd have figured it out on the first night. There must be a second monk with spots, and I don't see anyone else... must be me" - figured out on the second night
For 3 monks it's similar - if the only monks with spots were the other 2 they each see, then they'd have figured it out on the second night, so there must be another spotty monk, which they figure out on the third night.
In general, N spotted monks will realise that if there were only the (N-1) spotty monks they can see, they would have all figured that out on the (N-1)th day, so there must in fact be another spotted monk, which is them.

Can't think of a title that doesn't contain clues
Too much temptation to insert allusions/references/jokes that'd just make this easier...
So anyway, a riddle of my own device. Be gentle, I'll be annoyed if one of you lot one-shots it ![]()

Johnny was a Chemist's son
But Johnny is no more
What Johnny thought was H2O
Was H2SO4
A mosquito was heard to complain
That a chemist had addled his brain
The cause of his sorrow
Was paradichloro
Diphenyltrichloroethane.

The riddle of the mysteriously absent score-keeper
This is not actually a riddle, just wanted to say "Holy crap guys, there are like 83 unread items here"
But I guess that is more because I've been over here not signing in to Tangler with sufficient frequency than it is because it's been amazingly active in here.

How long do you spend in flight? If it's a working clock it should keep ticking forwards even if you do keep changing it back and forward with each timezone you cross into.
Also you never actually specified that the clock should be adjusted as if for local time at each timezone (I say "as if" because of the additional bit of setting it back some number of hours each time), but I assume the intent is that it goes forward by 1 hour with each timezone you cross.

Crime Riddle: The Thief in California
No-one ever told him anything about a break in, and he knows not only what he's a suspect for and when he's suspected of doing it.
