I'm still not putting on underwear, the evidence isn't substantial enough

What if you have to change in a locker room?
What if someone pulls down your pants as a prank?
What if someone finds out you don't wear it?

2) it'll be funny
3) it'll be funny
4) it'll be funny

That explains a lot. Just keep yourself covered up.
