This year's winning joke at the Edinburgh Fringe Festival has been deemed offensive by a Tourette's charity in the UK.

The following joke, made by comedian Olaf Falafel, won Dave's "Funniest Joke of the Fringe" award as voted for by the public:

I keep randomly shouting out 'Broccoli' and 'Cauliflower' - I think I might have florets.

Tourettes Action said it had received phone calls from parents of children with Tourette's, who were upset by the joke.

The charity's chief executive commented that it was not funny "to poke fun at people with Tourette's".

Is it acceptable to joke about almost any issue, or is there a line that shouldn't be crossed?

Caitlin McBride and Ian Power discussed this story in The Week Trending.

They also talked about the group of activists in Uganda calling for an end to white people being depicted as 'saviours' in Africa, and the criticism being levelled at Prince Harry and Meghan Markle over their carbon footprint.
