I know this is an old joke, but it always makes me laugh!
A newly married young couple go off on their honeymoon. Each has a small personal hygiene problem which they haven't told each other about. He has smelly feet, and she has bad breath.
In their hotel room he goes into the bathroom first to get ready for bed. While there he makes his mind up to tell his beloved about his feet problem. So he comes out and says
"Darling, before we get into bed, there is this small problem I feel I have to tell you about".
"Don't worry", she says, "I think I know what it is: you've got smelly feet, but don't worry, I love you anyway".
So then she goes off into the bathroom to get ready leaving her beau feeling a lot better. She too determines to tell her husband about her problem. So she comes out and says,
"Darling, I too have a small confession to make"
"Don't worry" he says, "I know what you're going to say"
"What's that then?" she asks.
And he replies "You ate my socks".
