Leftover Ice
Have you ever opened a tub of ice cream, not knowing that it was filled with fish heads? We have, and we’ll tell you that it’s one of the worst experiences in our lives. We’ve never felt such disappointment, but why not share that level of disappointment with your roommates?
Either purchase a tub of ice cream and eat its contents or eat your roommate’s ice cream. Next, fill it up with water and place it in the freezer until it’s rock solid. When your roommate is jonesing for a scoop, they’ll stand face to face with a tub of nothing but ice.
