I'm not sure if Advil will help

While visiting Redneck Cousin Eileen yesterday, she told me how she woke up with a headache but didn't know why. Her husband asked her if she hit her head on the wall during the night, to which she said, "No but - AH HA! I know what caused my headache! My cat headbutted me during the night! She has a really hard head!" And then plunked the cat on the head with her finger to prove her point.
