Fast food grease as art? Yep. Watch as artist Phil Hansen creates a huge replica of the Mona Lisa using nothing but grease squeezed from hamburger patties - and it only took him 10 double burgers to do it.
He didn't just do this for fun, though... it's actually an Arby's ad.
I don't know about Arby's in the states, but in Canada, Arby's doesn't make burgers at all. That's the point.
