Personally I am troubled that Richard Dawkins seems to have absconded with Stephen Hawking's wheelchair as well as his computer based communication system.
I leave you with the tweet of the year..."Dumb athiest. Why quote @richarddawkins? He just a retard in a wheelchair with a robot voice"— Ricky Gervais (@rickygervais) May 18, 2013
That seems unnecessarily rude to me.
P.S. By the way Ricky Gervais loves to rattle the cages of some of his more ignorant critics on Twitter and often retweets some of the most ridiculous things you have ever heard. This one was particularly funny.
