How To avoid TMF
 
Plaster over all (100%) of your electrical outlets
Wear oven mitts, horse blinders, and earmuffs, 24/7
Duct, Roll, and Cover (arms at your side, roll over strands of sticky duct tape until your body is completely bound and covered)
Faith-based abstinence
Move to a No-Fun Continent (e.g., a polar region) and hope that Nintendo's Fun doesn't follow you
