There are all kinds of ways to fake being sick/injured/dead to try and get sent home from school.
Pretending to have a weird rash that "suddenly came up" before the math test is not a good one.
Especially if you do it by rubbing your face and hands vigorously with Cheetos.
Your neon-orange "rash" washed off pretty damn easily when I took a washcloth to it.
And now you smell like the inside of a vending machine.
Nice try, though.
