I enjoy watching dancing with the stars, what about you?
I've only watched a few times, it was based on a British TV series Strictly Come Dancing.
I thought it was an original show, I didn't know it was based on another show.
Yes, and the format has  now been licensed to over 42 terriroties.
Do they use celebrities in each region or just the show from the U.S.?
It pairs celebrities with professional dancers in all areas I believe.
Oh ok, it's fun watching the popular people either do really well or fail splendidly. 
It became the world's most populate TV program in 2006 and 2007
Do you know any other fun facts about the show?
Well, they reached the top 10 in 17 different countries - so it's a very popular show
