a little off the subject... but I just LOVE your siggy

I saw that before. I think my computer has something similar built into it because when Zissou sits on the keyboard it makes a big long beeping noise and doesn't type whatever she's sitting on. Its an IBM Thinkpad T22. It doesn't keep her off of it though, it just keeps her from crashing it.
