Man wakes up and says nothing. Wife annoyed shouts, “You’ve forgotten what day it is haven’t you!”
Man goes to work and confides to a colleague, “I think I forgot my wife’s birthday.”
“Not a problem,” the colleague replies, "just go out and buy her a beautiful new dress and a pearl necklace.”
After work the man races home and showers his wife with gifts.
“Oh darling,” she replies, “what a beautiful new outfit to pick my mother up from the airport in!”
