Bizarre habits

While living with some friends about ten years ago I woke up one morning with the following in our flat after a night out:
1 traffic cone
1 set of lights from a small fairground ride
1 beer barrell
and a road sign for St Keverne Road. ( I can only assume its because my flatmate was called kevin and he took a fancy to it)

Pah can beat that, a friends birthday, woke up to find several bags of builders sand, several short scafolding poles (very handy to loosen things) several road cones and diversion signs including flashing lights and a random aussie bird. These items no one could remember collecting as we ended the night in a posh restaurant.
