Things that I can make with my underwear

Some people can perform with therir undies, (left to right Britney, Pink, and Gaga)

some people can salute or adress to millions with their underwear.

So, what can I do with my undies?

Well, with my undies I can sleep at a  summer night  and also I can open the door to my flatmate... anything else? Nope, just two things!

Note to myself: Maybe I should have taken care off my undies.
