Hmmm...lets see.....

Cosmo: knocked over my bedroom lamp and broke it to pieces.

Maxie: jumped out the second story window.

Those are the only 2 things I can remember but I'm sure if I thought long & hard, I can come up with a dozen or two more.

EDIT...oh wait...I just thought of something else. Cosmo ate my computer wires and I now don't have the use of my speakers OR my printer. (I knew I'd remember something else).
