You’d better laugh because, while Liam Neeson may not be a funny guy, he does have are a very particular set of skills; skills he has acquired over a very long career. Skills that makes him a nightmare for people like you. If you laugh now, that’ll be the end of it. He will not look for you, he will not pursue you. But if you don’t, he will look for you, he will find you, and he will kill you.
