Is anyone familiar with the show 'Adventure Time'?

One of my friends posted this on Facebook (via Tumblr) and after our field trip I felt like I should share it with all of you! Even if you are not a fan of the show,  I thought it was really cool that Lichtenstein's work was still being referenced using cartoon characters from today. And if you are a fan, even better! (Lumping sweet!) Enjoy :)
