This time next year...
Dear City Type,
I've got a cast iron system for making you loads of wedge. This is kosher, straight up. Honest, it really is. I realise that you've been kippered recently by some so-called financial experts and are probably a bit wary but you really can't go wrong with this one. Trust me.
Magic Beans. Easy - can't believe you haven't thought of it before. Anyway, I have some of these big boys and they're yours for a small consideration. Plant these, wait a few months and they'll give you a harvest of pure, 100% money. What's more, I have an inexhaustable supply of them. Send me a very large Jiffy bag full of £50 notes and I'll send you a bag of magic beans by return. This is the opportunity of a lifetime Would I lie to you? I've got an MBA! Look, I'll tell you what, send me the money now and I'll even plant them myself on my own allotment - saves you the bother. I'll send you the money when it's ready.
Look forward to hearing from you,
Honest Dick MBA,
PO Box 231
