Here's a precursor to episode 29 of Twin Peaks, in which Agent Cooper's cup of the coffee in the Otherworld turns out to be viscid. In a scene cut from Olsen & Johnson's Crazy House, "They find [Hans Conried] reclining on a divan, sniffing a rose, and painting blindfolded. Roco explains that he is endeavoring to paint the scent of the rose—its very essence. Another scene has Roco offering the boys a cup of coffee, then pulling it out of a painting on the wall depicting the same. To their disgust, the liquid turns out to be paint. An unfazed Roco says, 'I'm an artist, not a magician!'" (Hans Conried: A Biography by Suzanne Gargiulo). [Thanks, Jonathan!]
