In honour of Father’s Day, we’ve collected the biggest wrong'uns around.
Meet the maddest dads in sport...
Watford legend Troy Deeney recalls his dad picking him up from school in a "borrowed" Mercedes and hearing a banging noise coming from the boot.
"Don’t worry about that," said his father.
"He owes my pal some money so I’ve taken him on a little journey for the day."
Similar vibes from West Ham striker Gianluca Scamacca's terrifying dad Emiliano.
Last year he broke into Roma's training ground and demanded money, before going on a rampage.

One month later, Gianluca's grandfather Sandro joined him in the slammer after pulling a knife out in a bar fight.
Tyson Fury's 'orrible dad John spent 4 years in the slammer after gouging a friend's eye out in a car park.
He's out now, but he hasn't lost his old charm.
Big John recently told his son's opponent: "He's gonna bend your girlfriend over and do her like a dog, in front of you."
Max Verstappen's dad Jos has a lengthy rap sheet, including an "incident" which left a man with a fractured skull.
He also once ran over his ex-girlfriend and was charged with attempted murder.
She dropped the charges and married him, but they weirdly divorced 3 years later.
Ronnie O'Sullivan's old man ran a sex shop in Soho for many years, earning the nickname 'the Del Boy of porn'.

The film King Richard portrays Serena and Venus Williams' father as intense and uncompromising, but ultimately a dedicated family man.
In reality, he was an incurable shagger who sired between 15 and 19 children.

The father of former England cricket captain Nasser Hussain was a notorious taskmaster.
If Nasser didn't play well, the whole family would get "no chocolate and curry" that evening.
He once reprimanded him for "only" scoring a century and taking six wickets in a school match.
He'd get on with Heung-Min-Son's dad.
After Son won the golden boot, he was quick to denigrate the achievement and set some new KPIs:
"He must work harder and make more progress. If he is satisfied with what he has achieved now, crisis is on the way."
Now go to your room!
When boxing promoter Eddie Hearn turned 16, his famous father Barry insisted he fight him in the ring.
