lol, nobody wants to spend time with a grumpy old scotsman when they're alive, and they don't become any better company when they're dead. The first time I saw him I was a bit shocked, and maybe just a little scared, but after 3-4 times when I would see and hear him muttering, it just became a bit annoying.
The friend I was staying with at the time also saw and heard him so I know it wasn't my imagination :)
