What's the angriest you've ever been at football? Have you ever thrown a pie? A coin? Your false teeth? What?
That isn't a screengrab from a Big Train sketch, that really is a fans falsers. As you can see from the picture, Argentinos Juniors were losing 3-1 to Belgrano. One fan was especially annoyed and threw his false teeth at the manager- which is really gross. I guess sometimes shouting, swearing and flares just aren't enough.
I was once threatened with being arrested by an overzealous policeman, for giving the middle finger to a Rangers' supporters bus- but I cannot say that I've ever been angry enough to throw an inanimate object. "I hate you so much, let me find something to throw at you."
