I fell over.

Just now! And Yo can't stop laughing. It was really funny actually. It's almost 10:30 P.M, Yo 'n Chelsea fell asleep during a movie 'n I was trying to be as quiet as possible. Well after my tiptoe-ing around I was fiddling with the computer hard-drive which is sitting at my feet. So I'm sitting on my chair and have bent down to try and plug my camera cord in the back of it and... wait. My chair's history: the 2 legs on one side of it tend to bend inwards if you lean with it a certain way and it falls to one side. I was leaning backwards in my chair so I could get a better look at the hard-drive and I fell over. Feet up in the air and everything. I looked behind me to see if I woke up the girls and well, if you saw me you would laugh your stomach out too. Aaagh, lol this always happens to me! I goof up!
Yea, Yo's been laughing for at least 20 minutes. In her mind her imagination hits play, rewind and play over and over again.
Telling her that it wasn't funny or to shut-up makes her laugh even more. And then Chelsea laughs more cuz Yo is laughing then I laugh and then we all laugh and Yo laughs more, so we don't stop laughing! On my way to attack her, my legs got caught up in the blanket and I almost tripped. Again. Yo laughs more histerically. "Our stomachs are sore", but Yo's more so.
