I scared the pee out of her.

I was laying on the couch in the front room, reading a book, when Mia started messing with me.  She ran down the hallway and then came back and "scared" me.  I acted surprised and jumped up.  Mia thought this was hilarious, so she did it a couple of times. The third time she ran down the hall, I hid against the wall and waited.  When she passed me I jumped out and said "Boo."  I really scared her good......then she peed on the ground.  She got that look on her face like "Uh, oh I'm gonna pee," there was nothing I could do. I scooped her up mid stream and plopped her on the fireplace.  Then we both laughed.  I've never scared the pee out of anyone until now.
