We seriously love the way people think on Tumblr. First, one person posted the original Frozen movie still of Elsa and Anna in the snow. Then, someone realized it bore a striking resemblance to another Disney movie scene from Monsters, Inc..
Then, someone took it even further and made a hilarious cartoon-version of Sully and Mike Wozowski's faces as Elsa and Anna...
And then someone eventually just made a full on Frozen/Monsters, Inc. mash-up with Randall reciting Hans' most infamous line!
