Secret Birthday

How the internet can get you in trouble:

Me: Hello!
Chris Colleague: Hello!
Me: Happy Birthday!
CC: How did you know it's my birthday?
Me: It was on the internet, on Facebook.
CC: Oh, bugger.
Me: Were you not telling anyone?
CC: Yeah, I didn't want to have to buy cakes.
Me: Is it the big one?
CC: Yeah, 30.
Me: Hey everyone, Chris is 30! Cake time!
CC: You get.

And that's why they warn you not to put personal information on the internet.
