3 eggs and a little cash!

A women on her deathbed called her husband and instructed him to look under their bed and open the wooden box he found. He was puzzled by the 3 eggs and $7,000 in cash he found in the box, so he asked his wife what the eggs were for.
"Oh those", she replied, "every time we had bad sex, I put an egg in the box".
Not bad, the husband thought to himself, after 35 years of marriage, then he asked, "But what about the $7,000?"
"Oh that", she replied, "every time I got a dozen I sold them.
