Oldie but goodie.
The wife said to me today, "You never look at me any more."
I said, "Yes I do."
She said, "Tell me then, what's different today?"
"You've had a haircut," I replied.
"No!" she said.
I tried again, New shoes! Again, No. Erm,You've lost weight!
She said "See I told you."
" Ah yes a new dress!" I cried.
"No, I told you, you never look at me."
" O.K. you win. What is it? I said.
She sobbed and said, "I'm wearing a f*cking gas mask."
