This infographic from US sporting goods megastore REI isn't just amusing, it's in fact helpful. I never knew how to properly use a signal mirror before now. (Yes, I was a Boy Scout. No, I was not a good one. My only merit badge came for surviving the explosion of a can of beefaroni that some idiot Webelo pushed into the middle of a fire.)
Where the hell was I? Oh yes, the signal mirror. Don't forget the frying pan (a weapon in Left 4 Dead 2 Eighteen hits from it kills a tank on expert difficulty.) The key there is to not drop your shoulders as you start your swing. Do this by visualising swinging over the
ball zombie's head, in a slightly downward motion. To season your frying pan, fill it with vegetable oil and place it in a 350-degree oven for about an hour.
