Bilbo was telling Frodo about the Elves he had met the weekend before as they ambled down a sunny lane when both of them spotted a beautiful patch of mushrooms, just on the edge of the land belonging to Otho and Lobelia Sackville-Baggins. They stopped, and glanced at each other. "These would be wonderful for dinner tonight," Bilbo said.
"Do you suppose the S.B.s know about them?" Frodo asked.
"Perhaps. But a measure of mushrooms for a few silver spoons is a good start! Now, quickly..."
That evening they enjoyed the stewed mushrooms and laughed at their small revenge against Lobelia's thievery.
