The sound a bed bug makes when a librarian has an orgasm in the bed the bug is feeding in. Seeing as a librarian only orgasms one every 10 to 15 years. The bed bug with an average lifespan of 3 months only gets it's chance once in 40 generations to make this sound.

When it does get the chance to make this sound all other bedbugs the world over reply with a rendition of "Kumbaya my Lord Kumbaya"

Also the Bed Bug is written into BB folk lore and his story is told for generations to all the baby bed bugs.
