An old man is in a nursing home and his son is coming for a visit. The nurses put him in a chair and his head leans to one side so they put a pillow to hold it there. Then his head leans to the other side so they use another pillow on that side. Then he leans forward so they strap him in.
His son comes to visit and the nurses explain that they had to strap him in so he wouldn't fall out of his seat. He gives his father a notepad and pencil (his father can't speak) and tells him to write what his on his mind (his father has a painful expression on his face).
His father hands him a note that reads "They won't let me fart!!"
