OCC has a forum post from one of it's staff members showing what an Intel Core i5 750 looks like after his dog chewed on it. Thankfully the CPU was dead if wasn't it sure is now! You can check it out over here.
"My dog found it and decided to start eating it. She managed to get the heat spreader off, as well as to bend the poor CPU in the process. Anyway here are some pics after I pulled it out of her mouth, and wiped off the slobber."
