Because it does!
This is such a bit of obscure gaming humour, but even if the last MMORPG I played was years ago, I'm pretty sure if there was an exploit like that, there'd be people who were willing to look stupid if they could have an advantage.
And the sight of all those players prancing around with their hands on their arses... Ouch, ouch, ouch! I laughed so hard that it hurt.
Gianna, how do you come up with this stuff, woman?
