Why does Heather's knee pop so much?

My friend on WolfHome, Heather (aka Affliction) just went:

[2:36pm] Affliction: Why does my knee pop so much

And so I shall answer it for her.

Heather,

Your knee pops so much because you are a very vaginal young lady.

Sincerely,

Chrissiii.x

And why did you have to pee on my blog? It's all wet and urinal now D=

Also, I'm scared of the sound that just came out of my mouth.
