I decided to take a look at these supposed "epic memes" from mad_liberals, and I have to say, I'm quite thoroughly disappointed. I expected a lot more than lame video edits of movie clips and imagined things of what they like to think Democrats might have said.
It just reminds me of a critique of the Half Hour News Hour that I read once. The critique basically boiled down to "liberal humor works because they make fun of things conservatives actually say; conservative humor doesn't work because they have to make up words to put in Democrats' mouths to make fun of them for it". There sure is plenty of the latter in mad_liberals so-called "epic memes".
