mc5 - ... so help me God.

I so have not run out of puns for this game.

I worked for a while in a chemist's shop, but they dispensed with my services.

I spent a little time as a jobbing artist, until I drew my last pay packet.

I bought a veterinarian practice, but closed it down when I found I'd been sold a pup.

Moving on I became an orchardist, but that turned out to be a lemon.
