You go to Scotland, like I did last September, and you take a picture of the Loch on a cold, wet and foggy day. When you get home, you title it "Loch Ness, no monster" and show it to all your friends. They will point out a mysterious dark spot on the water that you will swear must be just a log...
Loch Ness, no monster
I've got a "ghost" from Loch Lomond too.

I believe in ghosts, because I believe in memory.
