One summer they rented a little blue tug boat and put a small oven on it and drove it all up and down the canal selling fresh croissants to passers-by on the towpath. They hung a big sign on the side that said “Croissants, £1” in purple felt-tip. Sometimes there would be other boats in the way and they wouldn’t be able to reach the land, so they had a couple of big sticks, one with a little bucket on the end for the pound coins, and one with a little basket to put the croissants in, and reach them over all the way to the bank. Tim said they sold a croissant to David Milliband, once, but I didn’t believe him.
