Popular student nightmare, each year, oddly enough some time in May. Can result in relationship termination, loss of great deals of money, cameras, phones and limbs. Not really the best night ever, but reassuringly expensive.
Tickets usually cost around £35, but can be found for as much as £50. However, it is recommended that you actually secure buyers who aren't skint students before going ahead with such a deal. (see MrTExploited)
