"Is it pretensious of me to say you don't know how to fucking spell, you illiterate cocksucker?"
Tim Robbins hits back at someone who accused him of being "pretensious", as part of a Jimmy Kimmel series in which celebrities are asked to read out offensive tweets about themselves. Bill Murray's reaction is equally great, naturally.
On a similar note, in case you missed it, James Blunt's sharp smackdowns to Twitter abusers last year were infinitely more interesting than his music.
