Step 1: Be a football fan. (A fan of the Washington State Cougars, in this case.)
Step 2: Watch your team get blown out (Washington State lost tonight to Stanford 55-17) and become increasingly depressed.
Step 3: Give up completely on football, dignity, and the entire concept of civilized society and just dump a giant plastic sack of popcorn on your face because it's easier than using your hands to eat.
