Mood Detector

My sister sent me this joke:

My husband, being unhappy with my mood swings,

bought me a mood ring the other day so he would be

able to monitor my moods.

We've discovered that when I'm in a good mood, it

turns green and when I'm in a bad mood, it leaves

a big frickin' red mark on his forehead. Maybe next

time he'll buy me a diamond.

I don't know why I laughed since I saw the punch line coming. I'm easily entertained!
