How to fake an injury to get out of gym class
Get an ace bandage without your parents knowing.
You don't have to spend up to $10 for a stupid bandage at walmart, just buy a good, sturdy $2 one at the pharmacy.
Get a pair of flats or flip-flops to wear on the day that you want to be " hurt ".
It would look strange and suspicious if you wore neon sneakers with a big ace bandage around your leg. Wrap the bandage around your ankle a few times, then wrap it around the base of your foot.
