What in the what now?

At this stage, you probably think you have seen every 'Friends' cast pic around.

The nineties sitcom stars no doubt had many a photo shoot together during the show's ten-season run.

There are the ones from the early days:

 

The milkshake sharing one:

 

The one of them sharing a bed:

 

The one with 'The Rachel':

 

The one on the streets of New York:

 

And then...

There is this one.

 

Was there a 'Deadwood'/'Friends' crossover planned we never knew about?

It looks like it was taken in the later seasons, so they really should have known better.

Needless to say, the internet folks have been having a field day with it.
