Big Tex..... Carpets on the Ceiling........only for me here after too many beers.
Funny I have this rather unattractive birthmark on my arm its not all that big and out of sight at the top of my arm, but in P.E or Games in my infant school, I used to get teased about it, so I ended up telling all my mates that it was a "Bionic patch" and I had Bionic powers, could run fast/jump high etc.......(The Six Million Dollar man was on at the time on TV) ....AND IT WORKED. I pointed to it, and they shut-up.
So I'll have to add Birthmarks are over-rated (but not in Junior school aged 6)
