So, what's your biggest dummy moment??

The darn cat used to walk accross the cars every night and leave kitty prints all over them!! "I'll teach him a lesson" I thought, so I picked him up by the scruff of the neck, placed him on the hood of the GTX, and gave him a spank on the butt!!! "I'm outta here" he said, but "Oops, no traction on the hood, time to deploy the claws"!! There's still kitty cat scratch marks down the center of the hood!! Who learned the lesson???
