My friends have been sending me memes.  What is a meme, you ask?

According to Wikipedia:

A meme (/ˈmiːm/^[1]), a relatively newly coined term, identifies ideas or beliefs that are transmitted from one person or group of people to another. The concept comes from an analogy: as genes transmit biological information, memes can be said to transmit idea and belief information.
