Something is BLOWING in the wind

I get into work this morning and realize I have to go to the washroom (#1) I sit and all of a sudden I feel something blowing on my "privates". It is blowing the whole time I am peeing. And it is icy cold. I'll I think (I think I actually said this out loud) "omg is there a rat in the toilot blowing on me". I finish and jump up all freaked out. Look down and there was no water in the toilot. It was air from the pipes coming up and blowing on me. THANK GOD. For those who know me, know that this was a dramatic moment in the washroom.
