So, the first time I was married...

I said 'Let's put a gold coin in this jar every time we make love. Then we'll count it on our first anniversary.'

So we did, and there was a lot of money.

There were lots of coins and a roll of 20's, 50's & the odd 100.

I asked 'Where did the notes come from?'

She said 'They're not all as cheap as you!'
