there IS a program like that for the Palm Treo...it's hilarilous. Everytime the card pops out you can have it throwup, burp or scream--very loudly.
I don't know of one for PPC but I can ask around.
Update: I posted a request at XDA to see if anyone can/wants to do it as I'm not aware of one currently for WM5. You can follow
the request here.
