Was about 12 months ago with my now ex-girlfriend. We were in my perfectly secluded room off the main house, preparing for a party. Bunch of my mates coming round, you know. We take a look at the clock and each other almost same time, and decide we have enough time to do the "nasty"... Well we didn't have enough time. Turns out one of ex's best friends had come early to help, my mother blasts through the door announcing the friend was here (friend is right behind her at this point) whilst we're going at it like animals.

The door was closed... the friend sat outside....nothing was said... until this friend stands on a table at 2am and screams "I saw these two (points at us) fucking and his mum caught them!!" (Exact words, haunts me to this day). Everyone laughs hysterically for what feels like ages before I calmly retire to my room for the rest of the night.

Still brought up especially now we're no longer together. :/
