The Hemlock Tearoom and Stationary Shop serves food that is impossible to eat. The eggs in particular are even worse than those of the Museum of Bad Breakfast, “where visitors can learn just how badly eggs can be prepared”.
In fact, when a bystander asks Lemony why he's spending so long in the bathroom, he replies "the eggs". The bystander nods sympathetically.
According to Lemony, the best way to ask for directions to the bathroom is “If I were a bathroom, where would I be?”
Theodora trying to “use a con”.
“You don’t know me,” she said in a bright, false voice. “I’m a young woman and this [a twelve-year-old Lemony] is my husband and we’re on our honeymoon and we’re both crazy about lighthouses. Can we come in and talk to you for a minute?”
“We love ink,” Theodora tried.
“You told Mr. Mallahan you loved lighthouses.”
“We love everything,” Theodora said with a desperate smile.
"There's an easy method for finding someone when you hear them scream. First get a clean sheet of paper and a sharp pencil. Then sketch out nine rows of fourteen squares each. Then throw the piece of paper away and find whoever is screaming so you can help them. It is no time to fiddle with paper." (As well as the Call Back later.)
After Lemony falls into a tree and Ellington climbs a ladder to get to him:
Ellington: That was quite a stunt. Where did you learn to fall into a tree like that?
Lemony: I've had an unusual education.
Ellington: Did they teach you how to get down?
Lemony: The best way is to wait for someone with a ladder.
