George Galloway had the phone put down on him this weekend by a TalkRADIO listener, in a row over Tony Blair's Brexit speech.
Former Prime Minister Blair gave a speech on Friday in which he called it a "mission" to persuade Leave voters to change their minds.
George's caller rang in to support Blair's speech, and expressed disquiet with the fact that Scotland was being "dragged" out of the EU when they voted to Remain.
Eventually, George had had enough.
He said: "Not only do I not understand what you're saying, nobody listening to you can understand your declamatory interventions.
"What I do know is that I can hear your knuckles dragging along the pavement."
At this point, the caller hung up, to which George had this to say:
"You're a caveman, and there's no point in hanging up because you can't make yourself clear."
