Synopsis: John and Elly talk about a recently-assigned habit Liz has of sucking her thumb as if she's a glue-sniffing anorexic who's got the clap. When John tucks her in, we find that Elly's habit of buying cheap sheets that pill up has left the thumb hidden under the covers covered in lint.
Personal Observation: When you remember that last year's attempted assault was ignored, one wonders what is wrong with these people.
