When you have sex with over 1000 men in a fancy mansion in London, UK in twelve hours time to set a world record, later find out you're pregnant, and then 9 months later everyone goes in for DNA tests to see who the father of the child is.
I was in a group of chaps who took part in this Guinness Book of World Records thing and the posh tosser in front of me ended up winning the London Baby Lottery.
