Description: Here's a question: If you ever encounter aliens, how do you show them that you are an intelligent life form? Answer: The Pythagoras Theorem. You draw a right triangle, then mark the hypotenuse with 5 dots and the other two sides with 3 and 4 dots, respectively (3² + 4² = 5²). This way, you will immediately convince them that humans are, like, really smart. Wear this Japanese "Hey Aliens! Check This Out" design and be prepared in case you are the first human to encounter aliens. Or buy it as a present for a loved one who is smart enough to represent humanity because you know what they say about first impressions.
