I told a friend I made $2,000 a month picking up dog shit from lawns. He said: "That's gross !" I said: "No, that's net." Boy: "Dad, will you help me find the common denominator?" Dad: "Don't tell me they haven't found it yet. I remember looking for it when I was a boy." I went into business prospecting for gold. It didn't pan out. I started up a business manufacturing tabletops for shops, but it was counter-productive. I set up a sauna business....................... but we ran out of steam.
