Years ago,my twin cousins who many years later became my training partners,excelled at baseball.....I mean the were extremely competitive and very talented......they won hundreds of trophies.....literally hundreds between the two of them.
So my old school uncle who was a little guy but one the toughest muthafuckers I ever met used to drink a pint of vodka and go to their games.......he always had another pint in his pocket.
Anyway he would be screaming fuck the umpire ,come on down and dirty,you cocksuckers that was a good damn pitch etc. etc.
They threw him out and banned him from the park.......an hour later he comes back wearing a wig as to disguise himself but his actions were the same so everyone knew who he was.

He`d tell the umpire "I`ll throw you a fucking smash you guy".
Moral of the story,the twins were devastatingly embarrassed.
I know Hanky`s not at that extreme, and his son is younger, but in many cases a father like this mortifies his kid as the other kids will tease him and bust his balls.
Support is one thing,acting a fool over 2 five year olds wrestling is quite a different story.
If this keeps up his son will resent him for it.
