Look at Her!
A man sitting at the window one evening casually calls to his wife, “There’s that woman that our next door neighbor is fooling around with!”
His wife dropped the plate she was drying, ran into the living room, knocked over a vase and broke it on her way to the window. “WHERE? WHERE? she demanded.
“Right over there on the corner. The lady in the blue dress.”
“YOU IDIOT! THAT’S HIS WIFE!!!”
“Yes, I know,” the husband said, with a satisfied grin.
