Here's a list of things that Roy Keane hates, delivered in no particular order.
2.) Coloured football boots.
3.) Hair gel.
4.) Any trousers that aren't grey
5.) Random acts of kindness on public transport... hates them!
6.) Any food that isn't porridge with water or stew. He likes stew.
7.) Baby otters.
8.) People who hold the door open for him.
9.) Waking up on a Saturday morning the day after payday with no plans or expectations.
10.) Paul Pogba.
Oh, and small children who ask him for his autograph. That's definitely his most-hated. Just ask Rory McIlroy, who's still dealing with the trauma of being dismissed by Keane many moons ago.
Having made a young fan's day at last week's British Masters by handing over his golf ball, the former world number one golfer reflected on his run-in with football's angriest man.
"I went and asked him for his autograph at the Portmarnock Links Hotel and he said 'no'. I'm sure he's alright, but it sort of stuck with me ever since," said McIlroy to BBC Sport about his trauma before the Alfred Dunhill Links Championship in Fife.
"I've had it go the other way, where I've asked someone for an autograph as a kid and they didn't give it to me and I've never liked them since. So if a kid asks me for an autograph, I always try to do it."
"I was surprised how that little moment last week became so big. But it just shows what such a small thing to me can mean to a kid, and that kid might be inspired to go and play."
It is Roy Keane, though, Rory.
