First-year students at St Andrew's University in Scotland staged a shaving foam fight on the university's Lower College Lawn to celebrate Raisin Monday.

The tradition is thought to date back to the university's early days, when new students would give senior students a pound of raisins as a thank-you for helping them to adjust to university life. In return, they would get a receipt written in Latin. Failure to produce the 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 a foam fight.

Raisin Monday is the culmination of the university's Raisin Weekend - an alcohol-fuelled rite of passage for new students.
