Of course, Bilbo throwing shade on his relations ranks up there with puntastic sarcasm, if we can take the definition of "pun" to include the different possible meanings of a word or phrase (and perhaps the intention of said word or phrase):

For ADELARD TOOK, for HIS VERY OWN, from Bilbo; on an umbrella. Adelard had carried off many unlabelled ones.

For DORA BAGGINS in memory of a LONG correspondence, with love from Bilbo; on a large waste-paper basket. Dora was Drogo's sister and eldest surviving female relative of Bilbo and Frodo; she was ninety-nine, and had written reams of good advice for more than half a century.

For MILO BURROWS, hoping it will be useful, from B.B.; on a gold pen and ink-bottle. Milo never answered letters.

For ANGELICA'S use, from Uncle Bilbo; on a round convex mirror. She was a young Baggins, and too obviously considered her face shapely.

For the collection of HUGO BRACEGIRDLE, from a contributor; on an (empty) book-case. Hugo was a great borrower of books, and worse than usual at returning them.

For LOBELIA SACKVILLE-BAGGINS, as a PRESENT; on a case of silver spoons. Bilbo believed that she had aquired a good many of his spoons, while he was away on his former journey. Lobelia knew that quite well. When she arrived later in the day, she took the point at once, but she also took the spoons.
