Edvard 'my whole life has been spent walking by the side of a bottomless chasm' Munch worked on this painting for three years (1932-1935) without ever finishing it.
It's called Uninvited Guests and in it he makes a fairly unequivocal statement: alcohol has been consumed, the wallpaper is weird, and I have a firearm, so don't come around here ad hoc with your smiley balloon heads and expect your shrift to be anything but short.
