It seems like it's been about two years since we last saw José Mourinho so much as crack a smile, but he properly cracked up in a charity joke-off with comedian and staunch Liverpool fan John Bishop in a 'straight face' competition for Stand Up To Cancer.
In a show that will be broadcast on Channel 4 this Friday at 7pm, Bishop and the Manchester United boss throw horrendous jokes at each other in an attempt to make the other man break from his steely stare, and despite initially expert indifference, it's Mourinho who buckles during one of his own jokes - 'What do you call a sheep with no legs'?
Love him or hate him, his cackling at the answer and Bishop's subsequent guffaw is thoroughly enjoable, and the full episode should be full of similar incidents.
Mourinho & @JohnBishop100 making each other laugh, might be the funniest thing we've seen all week.

The Portuguese manager will now be absent for up to three games having badly strained his underused facial muscles in the process.
