The joke is on comedian Bill Maher today, as he's gone viral after pics of him wearing a WIG were released online.

Bill Maher spent his Monday night grabbing a bite to eat alone at Craig's in West Hollywood. It was nice to see him out and about after the backlash of his harsh comments on late Stan Lee.

And Bill seemed like he was in good spirits. But all that is about to change. The paparazzi released the flicks of Bill wearing a wig - and immediately the comedian started trending.

People are making all sorts of cruel comments about Bill's new fake hair. 

But Bill - who is 62 years old - should be able to take it. He's been known to make cruel jokes about people in the past. For example, Bill dressed up as a deceased Steve Irwin (the Australian animal activist) on Halloween, just weeks after he passed away tragically.
