"Alfred! If you do not stop doing that I will kill you! Everytime you do that I get more and more pissed, eh!" Matthew yelled, having appeared to holler at his brother.
He was wearing a tan parka over maple leaf pajamas and carrying a hockey stick.
"C'mon bro! Its fun!" Alfred laughed, stopping as he was hit upside the head.
"I said to stop, eh! For the last twenty years you have been doing this! It's aboot time you stop!" Matthew pulled his hockey stick back, content now that he got to hit the idiot.
"Hehehe. You said a boot."
Matthew grunted before swinging his hockey stick again, hitting Alfred on the backs of his knees. When Alfred fell he brought the hockey stick down on his head, knocking him out.
From then on, at random times of whenever he felt like it, he would cross the border between America and Canada, doing to Alfred what his brother had done to him for years.
