There are some great quotes in this clip which sees David Mitchell answering questions about tax avoidance during an interview on The Last Leg TV show in 2105.
Bad language alert in this clip:
"Vanilla flavoured. Less than vanilla, unflavoured tax avoidance"
At the other end of the spectrum, "Gary Bartlow's evil flavoured" tax avoidance
Tax avoidance involves "50 shades of grey. And that's not an ice cream flavour anyone wants!"
"Legal loopholes allowing tax avoidance mean the government is “taxing conscience” – the more of a conscience you have, the more you pay – and that isn’t right"
"We're taxing being nice"
