The funniest 'Memes of the Week' is back for our last meme roundup of September. We have memes covering the most important current events of  this month -- the release of the iPhone 5, the NFL replacement refs fail, and oh why not, let's throw the presidential race in there too.

In other news, Grumpy Cat is grumpy, and the 1990s has problems we could only dream of. Ron Swanson is funny as usual and we can't wait to go see the new movie 'Pitch Perfect.'

End your week (and month!) with these memes. We promise you won't regret it. But do take our advice, and don't even try to teach Grandpa how to print...
