1. Bob explains the fact that he can't remember what happened yesterday by saying that he must have been kidnapped by aliens, who performed surgery on him and then erased his memory of everything that happened the day before returning him to his house.
2. Mrs. Jones hears strange noises at night such as the creaking of the floor downstairs and rattling of windows. She explains these phenomena by hypothesizing that there is a 37-pound badger that inhabits the house and that emerges at night in search of Wheat Thins and Oreos.
