Here's the best conversation I've ever heard:

Nelly: I have something that's going to change your world (giving Icy a Tampon)
Icy: What is it?
Nelly: A tampon, you use it rather than a pad
Icy: Screaming: It's SO BIG!!
-icy is crazy because it’s one of those tiny OB tampons that's thinner than your pinky finger and only 1.5 inches long
Nelly: you have to try it. You'll never want to use a pad ever again!
Icy: Never, never, never!!!!!!
Nelly: Pleasseeeeeeeeeeeeeeeeeeeeee!! You'll love it!! Do it for me! PLEASEEEEEEEEEEE!!
Icy: only if you'll try a pad
Nelly and Mariel: EWWWWWWWW!!!!!! Grossssssssssssssssssssss!!!
Nelly: FINE, I’ll try a pad if you'll try a tampon
Icy: but wait, when you use a tampon, how do you go pee?
Nelly: What? Why would you not be able to pee?
Icy: because the tampon blocks it
