Comedian's dad tweets hilariously underwhelming compliment about his son, goes viral

Nobody knows how to give compliments quite like the British.

There's a knack to it. It's important not to show too much enthusiasm, for one. You've got to hold something back. In fact the more reserved you can be, the better.

UK comedian James Acaster's father just gave a masterclass in this fine art.

It started when presenter Richard Osman tweeted an endorsement for Acaster's new Netflix stand-up show Repertoire.
