Not on a bike ride, but one time I was standing at an intersection in downtown St. Louis waiting to cross when I heard something sliding down the street. It sounded like a flattened soda can sounds when you kick it. I looked down and a cell phone slid right up to my feet. It had come off a car pulling out of the parking garage across the street. It was still on and everything.

I took it back to my office and perused its phonebook. Ironically, there was a number listed as home. I called it and left a message explaining that I had the phone. The guy came to my office the next day and picked it up. I had to laugh because I have HOME in my phone as well.
