Don’t do this one yourself if you catch an AdSense cheater, but go ahead and laugh at this one: http://forums.digitalpoint.com/showthread.php?t=11041.

Just remember if you ever think about cheating AdSense, Google will take your unpaid earnings from you and it is not impossible that they will pursue legal action as well if they catch you doing anything against the TOS. Not to mention, you’ll annoy any AdWords advertisers who happen to see what you’re doing. You never know what your readers are doing, so keep things legit.
