7. The Spit Burger (Dumb & Dumber)
Here we are with Dumb and Dumber again. En route to Aspen, Lloyd and Harry decide to stop for food at a truck stop. Prior to eating his lunch, Harry spills some salt and Lloyd informs him that, to avoid bad luck, you have to throw salt over your shoulder after you've spilt it. Being incredibly dumb, Harry throws the entire salt shaker over his shoulder, instead of just a pinch of salt, hitting an aggressive local trucker named Sea Bass, who is angered and approaches Harry, asks him if he's going to eat his burger, then spits a big green blob in to it.
