3. Turtles and mushrooms can kill you just by touching you anywhere other than the bottom of your feet.

5. You can only have unclothed sex after applying a patch.
6. No matter how heinous a crime you pull, even directly in front of cops, they will forget what you look like and what car you sped off in if you stay out of their sight for 20 seconds.
7. Regardless of shoe type, the soles are always so slippery that standing on any slope greater than 45 degrees will cause you to slide like an ice skater downhill.
8. Some types of molten lava will not kill you, even if you fall completely in, as long as you jump out quickly.
