Love him. But not as much as Bill Maher. Bill is appointment-viewing, but I find John Oliver is not. I love that I can catch him on the reruns throughout the rest of the weekend, usually, at random opportune times.
That said, he's not "fake news." He talks about real news items, but with strictly heavy doses of sarcasm to make his point.
"There is no use trying," said Alice; "one can't believe impossible things." "I dare say you haven't had the practice," said the Queen. "When I was your age, I always did it for half an hour a day. Why, sometimes I've believed as many as six impossible things before breakfast." --Alice in Wonderland
