The Grandfather Paradox

Warning: Do not attempt to visit your grandfather's house in the past, as it may cause unintended consequences, such as:

• Stealing all his beer from the fridge
• Forcing him to watch an endless loop of your favorite music videos
• Getting him to eat an entire pizza by himself in one sitting
