Mentioned this in the live score thread yesterday, now got a picture of it. This is from Almeria v Cadiz yesterday in the Spanish Second division.
The linesman spots something in that little group of players outside the box. There's not a single player (apart from the keeper, obviously) inside the box. Decision? Red card to one of the Almeria players (in the red and white, not that you can see the colours very clearly), and penalty to Cadiz. It's not even a borderline decision, is it?

Luckily although Cadiz scored the penalty it didn't prove too costly for Almeria as they still won 2-1.
