Students from St Andrews University take part in a foam fight as part of the traditional Raisin Monday celebrations in St Andrews, Scotland November 22, 2010. The tradition dates back to the early days of the university when new students would give senior students a pound (0.45kg) of raisins in gratitude for their help in adapting to university life, in exchange for a receipt written in Latin. Failure to produce such a receipt could result in a dousing in the local fountain. Nowadays the raisins have been replaced with a bottle of wine and the dousing with foam. Recently-engaged Prince William and bride-to-be Kate Middleton, who met at the uni as undergraduates, took part in the celebrations in 2001.
