What is the BEST way to checkmate?

Hi All. I'M trying to find out what the BEST way to checkmate in a position is. Maybe it is a classic en passant mate, or maybe it is a spectacular underpromotion frenzy. Whatever the case, please post your ideas below. I don't know whether you can post a position, but if you can please feel free to do so.

Personally, I think that the best way to mate is underpromoting to a knight on g8, with a bishop on h8 delivering double checkmate onto the king on f6. And it is the only way to amte.

The best are mates that surprises me.

Start a collection of your best checkmates. I know I've had a smothered mate or two, but I wouldn't be able to find it if you paid me.
