Bacon In Film. "Gummo" (1997)

For no good reason what so ever I watched the film "Gummo" last night after a couple glasses of diet Materva spiked with some Rebel Yell. I don't particularly like this movie much, but it had come up in conversation for some reason and I watched it to refresh my memory. I was also looking at the wiki for the film and found the this quote-

"Werner Herzog praised the film in a conversation between himself and Harmony Korine, published in the November 1997 issue of Interview magazine. Herzog spoke of being especially moved by the bacon taped to the wall during the bathtub scene."

Of course, I made note to keep an eye out as the above capture attests. I always liked Werner Herzog, "Stroszek" is a great film. But anyways, that is bacon taped to the wall. Without purpose or explanation.
