He was fantastic on The Daily Show as a correspondent, he was even better as a stand-in host while Jon Stewart was away, and he's really hit his stride with his own show, Last Week Tonight on HBO.
This week, after tackling some of the more heavier news items, John Oliver lightened things up somewhat by looking at Singapore's anti-gambling ad that caused a bit of s stir last week.
We love that HBO make this content available online so soon after broadcast. It's just a shame his show is only once a week.
