After the television series Lee and Cheryl decided they were going to have a caravan site. They approached the young estate agent again - the one who let them use his land for the snail farm, if you remember - and assured him they were serious.
To cut a torturous story short, they tied the estate agent up for well over a year (not literally tied), the seller of the land, architects, solicitors, the local council planners - only to pull out at the last minute when they realised the seller of the land was not going to spend a lot of money getting the land ready for caravans. They had not spent a penny but wasted a lot of peoples time.
