Internet memes are pretty powerful things. Powerful enough that Grumpy Cat was one of the most popular stops at the 2013 South By Southwest Festival.
Made popular on sites like Reddit, Grumpy Cat is exactly what he sounds like, a grumpy looking cat. The cat's face looks like it's stuck in misery. Thankfully, the cat is bringing joy, rather than the bad news the face suggests.
If Grumpy Cat can get a line this big, thankfully Psy isn't at the festival this year.
