LONDON - MARCH 18: An adult Tyrannosaurs Rex robotic dinosaur performs in the O2 arena ahead of the forthcoming European leg of the live show 'Walking With Dinosaurs' on March 18, 2009 in London, England. The live arena show, which has already toured throughout North America, tours the UK from July 2009. The £10 million show features 15 mechanical life-sized dinosaurs and is based upon the hit BBC TV series of the same name.

This is the funniest thing I have seen coming from a wedding in a while. The Maid of honor was not mad at her sister or anything. Her sister asked her to be there and made the mistake of telling her, “you can wear whatever you want”. Well, she did just that and showed up in the hilarious T-Rex costume that I am sure you have seen before. I do wonder if she had a dress for pictures?

Would you be mad if your sister wore this?
