Maybe Van Gogh cut his ear off because someone traveled back in time and whispered a Drake song in it.

Van Gogh's girlfriend: Oh my love! Why did you cut off your ear?! Van Gogh: pardon?

Van Gogh hands a wrapped up box to his girlfriend. ""Vincent, please tell me this isn't another ear."" ""What?""

I'm a traveling art collector, but not doing so well... I'm always in need of Monet to buy Degas to make the van Gogh.
