We don’t know which is more painful, getting electrocuted or living with James Corden? It turns out that one man has experienced both, as it was revealed on James Corden’s late night show that the ‘Mamma Mia! Here We Go Again’ star Dominic Cooper and talk show host were former roommates.

Corden decided to test Cooper’s memory of the period by having the pair face-off in a quiz to see who knows the other better. Wrong answers would be penalised with a strong electric shock impulse.

‘Mission Impossible Fallout’ star Rebecca Ferguson was the quizmaster and even she found it painful slash hilarious to watch the guys compete against and shock one another.
