Tim: Tell us about this, Al.
Al: Well, this is an old hog oiler.
Tim: Now, how does this compare with the one in your mom's house?
Al: You see, the way these work is the hog comes up and it rubs against the rollers like so. And the skin becomes moist.
Tim: Oh. So, the hog actually looks at this as kind of an "oinkment." [Al laughs]
