Bwaahhaahaha... that's a riot... :-)
*grin*
I'll share one more to show how incredibly dense I was to not have learned a thing about not hosting parties.
I had another slumber party when I was 14-ish. We all packed into the den and decided to watch Friday the 13th.
There was a window right above the TV that was left open since it was cool that night.
Now, I had warned all of my friends that my dad was a weirdo and he would definitely try to scare us at some point, so we kept an eye out for him.
Well, after a while we let our guard down and my dad snuck out the front door and went around to the back of the house where the window was.
Just as that scary ch-ch-ch ha-ha-ha sound came on, he jumped up making a hideous roaring sound and nearly came through that open window. Did I mention he had so courteously put on a Michael Myers-type mask?
He later said that the funniest part was the mass collision of bodies that leapt up, trying to get out of the den at the same time, so that no one managed to get out without some kind of bruise.
