21. Beer Goggles
When you hear of beer goggles you probably think of the silly goggles people wear that look like beer mugs, or the expression used to indicate your level of intoxication the night before when you’re trying to justify a mistake, but probably not literal beer goggles; which is why these tiny beer goggles make the perfect gift. You can use them to determine ownership of drinks while reminding everyone not to live out the expression at any point in the night–subtly of course.
