I have gone postal on something at some point.  I think an old laptop?  I saw a guy throw a microwave off a 4th floor balcony, then go down and pick it up and throw it to the ground three times.

On the third toss, he caught part of the loose metal on his arm.  He ended up needing 32 stitches as he almost bled to death.  Yes, drinking was involved.  I saw this microwave by the dumpster at home and it brought back memories.  Have you ever lost it?
