Heavy Spoilers from 204, so, don't read until you finish it!
Did you remember the Screwdriver which Sam "borrow" from Little Sam? When you try to return the Screwdriver, Sam comments for his own sake he will never return the screwdriver to himself. The point is, he did! No to Little Sam, but to Past Sam! (I like to call them "Season 1 Sam & Max" ^^!) But this detail which be THAT curious to me, except for the fact how Present Sam & Max has to return to the Spaceship: They had to "replace" Past Sam & Max from 102 to 203! Which means, when Past Sam & Max takes the elevator, no matter where they go, Present Sam & Max are "there" too!
In resume, I think, in someplace in the future (Or even since 102) there's 2 Sam & Max, and one of them we don't play with them, had a Time Machine AND a screwdriver (OF EVIL!)
I'm the only one who notice that. I'm overthinking everything again as usual?
