Silent Psychiatrist

Alright listen up, numbskull. This "joke" is playing on the silent letter "p" in the word "psychiatrist." Get it? You probably don't, because you're as sharp as a marble. Psychiatrists are supposed to listen to people's problems, but in this case, the "p" in their title is silent, just like they are when they're trying to be discreet in the restroom. You're about as dense as osmium, I swear.
