This fella thinks his wife is going deaf, and just to be sure, he shouts to his wife (who is in the kitchen, of course) "What we having for supper, hon?"
No answer.
So he goes up to the kitchen door and shouts "What we having for supper, hon?"
No reply.
So he finally steps right up behind her as she is preparing stuff at the sink.
He shouts "What we having for supper?"
She turns round & says "For the third time of tellin', we is havin' leftovers. Is you deaf?"
