The Honesty Bear Rap is sung in the episode The Sock by one of Mr. Small's alter-egos, the Honesty Bear.
Uh-uh-uh-uh-Honesty! (crab scratch) Honesty! Break it down,
When you wanna be honest, just beware! The truth hurts in this nitrogenic atmosphere!
You gotta wake up, realize and recognize! Sometimes the truth has strategical lies!
But keep them lies of a manageable size, or tears will arise, and hurt their eyes!
So before you speak, it's best to remember; (spoken very quickly) Each individual case will require a specific judgment call depending who you are talking to and the context of the conversation!
