Sort-of memes that are cracking you up at the moment

1) The thread is called 'sort-of memes' so could encompass pretty much anything, not just what you think a 'meme' is.

2) The definition of meme is: a cultural unit (an idea or value or pattern of behavior) that is passed from one person to another by non-genetic means (as by imitation). Not just a funny picture that has been written on.
