Made an assumption based on your ID English so one just for you.
There is this English fan watching the England rugby team play on the
TV in the pub. He is all decked out in England colours and even his
little dog is wearing an England shirt.
The match goes on and every time England get the ball, the little dog
jumps up and runs around barking. Eventually, England get awarded a
penalty and Johnny converts it. The dog goes absolutely wild - he
jumps up on the bar and does somersaults, he high fives his owner - he
is just ecstatic.
One of the other customers goes up to the guy and says "That dog is a
real England fan isn't he - if he does that when England score a
penalty, what on earth does he do when they score a try?"
"I don't know", says the guy, "I've only had him three years".
