As long as you know they are 'jokes' it should be OK.
This one (Leonid Kubbel again) is no joke, it's all legal.
White takes back his last move and instead plays a move that mates in one.
The beauty is in the orginal idea and the fact it only has one solution.
(a piece has been taken, but it's not just any old piece, it has to be that certain piece.)

Correct!
White retracts his last move, plays another move that checkmates Black.
White take back 1.exe8(N)=Q giving us this position.
If the piece on e8 was a Bishop or a Queen then the d7 pawn could not move to d8.
White plays 1.d8=N mate
Again if the piece on e8 was a Rook then it is not mate.
The piece replaced on the board after White retracts his move has to be a Black Knight.
Beautiful.
