Wife's picture

Wife: 'You always carry my photo in your wallet. Why?'

Hubby: 'When there is a problem, no matter how great, I look at your picture and the problem disappears.'

Wife: 'You see how miraculous and powerful I am for you?'

Spoiler:

Hubby: 'Yes! I see your picture and ask myself what other problem can there be greater than this one?'
