Most Bizarre Business Ever

What's the most bizarre business that you have ever had?

I remember how I got OFB for the first time in 2010, and I was so happy! It was my first and only expansion pack. I have two stuff packs, Kitchen & Bath Interior Design and H&M Fashion, and both of them come from my Best of Business collection. Anyway, one of the first businesses that I started was Daniel Pleasant's home pool business. I just made the Pleasant family's outdoor pool a business, and I tried to get customers to enter the pool. I also locked the doors to the main house, because I wanted the customers to focus on the pool. The longer customers spent inside the pool and had fun, the more simoleons I earned.
