What's the Weirdest way you've Gained and Lost Weight?

I was on an Ice Cream kick for a month where I ate Ice Cream everyday and I gained 20 pounds. The next month I got on a Beef Jerky and Handi-snack (Cheese and Crackers) kick where that's all I ate at work and I lost the 20 pounds I had put on.
