I'd bought some apples from a store on campus and was carrying them in a plastic bag while waiting in line to pay at a different store. I heard a thud, and looked down, and there was an apple on the ground. I picked it up, and then felt the bag for holes. I didn't find any. I also counted the number of apples in the bag, and the number of apples I remembered buying were still in there. I knew that it was very, very unlikely that the apple had just appeared there, but I did assign a very small probability that I'd just seen something that didn't fit with known physics. A couple minutes later, the same thing happened again - another thud, another apple appearing on the floor. It only happened twice, though.
