There's a madrigal called "Two Lawyers" sung by Clam Chowder: on completing a law case on opposing sides, the two lawyers saunter off to lunch together. The client of the first lawyer is shocked to see this, but the client of the other replies that it shouldn't be surprising, for two lawyers are like a pair of shears: they never cut each other, just what lies between.

Sorry I haven't more details, but the image is a nice one.
