Turns out Dominic Cooper and James Corden go way back. They've been friends for ages, they used to live together, and Cooper even introduced Corden to his future wife Julia Carey.
Anyway, what better way to put that friendship to the test than a quiz where the loser gets a sharp electric shock?
In the clip above from The Late Late Show, the pair do their best to answer questions about each other. Turns out despite their closeness, Corden can't name Cooper's Preacher character, and Cooper can't remember the middle name of Corden's son Max (who also happens to be Cooper's godson).
Needless to say, there are plenty of shocks all round.
