I once had some web designer steal a site design we paid about $4K to develop. we're talking free flowing graphics type stuff. I know the designer personally, knew it was all original hand made artwork in PhotoShop, no clip art involved.
Anyway, when I called the site owner and told him to get our stuff off his site ASAP or face the consequences he started with "I know this web designer from Church! He wouldn't do anything like that!" at which point I started yelling "WELL HE MUST'VE SLEPT THROUGH THE PART ABOUT THO SHALT NOT STEAL!" and then it got fun. Then they started telling me it would take so many days or weeks to do this and that to which I kindly told them my lawyer apparently works faster than his developer and it would probably cost a lot more. Then I kindly offered him options to see if he would prefer paying the developer or my lawyer.
It was off the site within a couple of hours.
Luckily for him I was in a good mood that day. :)
