I've been browsing a lot at Know Your Meme. It is an absolutely hilarious site for all things internet humor. Some of my favorite memes are...
Milhouse is not a Meme
Not sure if
Paula Deen Riding Things
Zuckerberg Note Pass
Socially Awkward Penguin
Okay... so there are really too many to name, just check the website out!
I also found Cleverbot through the site and had a couple conversations with it, it can be pretty smart and random and just funny at times.
