My sister and her boyfriend of 2+ years decided on Friday that they would take a spontaneous weekend trip to Vegas this weekend.
I guess during the trip, her girl friend called her and they joked about a secret vegas wedding.
This friend then goes on facebook a day after my sister puts a status update of "Vegas on a whim", and types, "hey Mrs. Hislastname"
A small number of people notice this post and comment.
Then my sister decides to take the joke to the next step and actually change her relationship status to married. (without saying a "word" on facebook)
I get on this morning and there is a firestorm of hilarious posts! She came clean once she realize that we are friends with about 40 extended family members, phone calls were being made, and news broke to our grandparents!

Re: My sisters vegas-wedding joke...
That's so funny!
I have too many extended family members on mine, they would all be freaking out. They'd be halfway to Vegas or Jersey if they read that!!
