Well, if we're on silly games, lets have this one.

Cheese Rolling!

Around May day , the people of Coopers Hill, Gloucestershire and many, many outsiders gather to compete in the annual Cheese Chase.
A number of men gather at the top the hill, and a 7lb wheel of double gloucster cheese is bowled down the hill. The men give chase, and the first one to catch the cheese, or cross the finishing line keeps it. The young farmers association, and rugby teams are firm favourites for this.

There is a seperate competition for women, as they're not stupid enough to join in the mens one...
