my best one happened on one of our lads trips down to my mates house in polzeath, cornwall.
we'd been getting battered all evening playing drinking games (alcohol stash:

then to make things worse one of my mates came over to try and help me out. he picked me up straddle-style, with my legs either side of his hips. i started shouting again as he was pulling the hairs out of the backs of my legs due to the way he was holding me. he tried to put me down but slipped and that resulted in my head hitting the wall.
woke up the next morning with a massive purple lump on the top of my foot, and a video of it all happening.
here's a photo of my foot the morning after. it's not easy to see the lump even though it was massive, honest, but just look how raised the bit before my toes is on top of the foot:
