You met someone you least expected to see in your birthday and spent some amuzing time together.

you bought a house

you found an old rusty metal box full of WW2 ammo in the ground

You have pre ordered Retro City Rampage and for some reason you now actually own it when it isn't released yet

You knew your "get out of jail free" card would come in handy one day, so you got off the hook when you bitch-slapped Putin today. It even came with a personally signed and framed photograph of the event.

Your child was born on your birthday?

Someone made a surprise trip to visit you for your 30th birthday, but you are only 29 (or similar).

This actually happened to my grandfather - on his 79th birthday my uncle flew in from overseas and surprised him believing it was his 80th birthday, I am told Granddad nearly had a heart attack when he opened the door.

Your girlfriend/fiance/wife said she will have some naked exercise with her girl friend in your bed and you can watch.

A guy in a coat flashed you, then you laughed like a mad man and he ran away.

You opened a door only to find out that the doorway had been completely covered up with bricks.

Your shadow wished you a happy birthday.

Someone you thought was dead reappeared in your life, and he/she was not really dead?

Braaaains! :D

Thanks and for the giveaway AND happy birthday, Starmaker!

Here in London a room full of people are laughing hysterically at your answer. Thanks for that :D

Your friends/coworkers/... gave you a surprise present. A girl with a tape recorder came to you, turned on the music, and started dancing.....lap dancing.

Your recently lost pet returned home... with a mating partner?
