The Mrs. once was so bored she couldn't decide whether she was bored senseless or bored out of her skull.
So she said she was "bored skulless."
Which oddly made sense . . . so bored my brain collapsed into a black hole and swallowed the skull.
I used it for years afterwards until she finally found out where it actually hurt when she hit me.
One I'm not sure I believe, a man calling into a radio show said his wife was so upset with the next door neighbor she wasn't sure whether to kick his ass or merely give him a piece of her mind.
So she said "I'm going to go over there and give him a piece of my ass!"
