Why did Karan Johar cry?

Believe it or not...SRK drove his best buddy KJo to tears. Wondering why?
No, this isn���t just another Bollywood jhagda that will make national news. In fact, it is all about loving your friends, and their movies. To cut a long story short...last week Karan saw the special screening of Billu (minus the Barber), and apparently he was so moved by the film in the last twenty minutes, that he cried.But, KJo does seem to get emotional while watching movies. Remember, he also admitted to having cried while watching Taare Zameen Par.
Apparently there were a lot of sobs and sniffles heard even amongst Gauri and her friends... kya yaar Billu, what are you doing to our lovely ladies? Now that they���re so moved by Mr Billu, are the women also ready for a new hair-do? The BB style, we mean!
