In the mid-'90s, I remember seeing Wesley Willis sitting at Lounge Axe, barefoot, drawing these huge pen-pencil-magic marker cityscapes. Before and later, I remember him seeing me on the street, grabbing the back of my head and saying, "lemme head butt ya". And I did. Everyone did.
[I hadn't thought about him for years until Mark Noble sent me this link. Thanks Mark.]
