The Big Bang Theory cast celebrated 200 episodes with a big party

BBT200 sounds a bit like a new Star Wars robot. Instead it's what all the cool kids are calling the huge celebration marking The Big Bang Theory's 200th episode.

Oh yeah, 200 whole episodes have been lovingly crafted, with the milestone episode to be centred around Sheldon's birthday.

The show's not going anywhere, of course – series ten has already been commissioned – but why not stop and take a minute to celebrate the big numbers? So with cake, cats and cute pictures the cast partied...
