An American is typing on a computer when he flies into a rage, shouting "How the hell am I misspelling color"? A Canadian takes a quick look at the screen before rolling his eyes and walking away, saying "that sounds like a u problem".
You have to hunt down a troll and kill it with a gun. After you find it, you accidently lose sight of it. In rage, you fire your gun. The bullets hit the troll and it dies. What do you tell the person who sent you on the quest? - I lost gun-trol.
