No need to be a mathematician to understand the joke with this design featuring the following text: "I Don't Do Math ... My Erdős Number Is Empty Set". Paul Erdős, was one of the most prolific mathematicians of the 20th century, known for his practice of social mathematics. An Erdős number describes a person's degree of separation from Erdős himself, based on their collaboration with him, or with another who has their own Erdős number. Make others do a double-take about the mathematical world with a dose of wry geek humor with any of these Erdős number saying gifts!
