A mob boss is attending the funeral of his longtime underboss, a man he had called his best friend since the two were kids.

As the service is drawing to a close, the old don spots an FBI agent in the crowd of mourners.

Angered, the boss walks over to the agent and says "What the fuck are you doing here you piece of shit?". Without skipping a beat, the agent goes "Oh I just came to pay my respects. We've been working with Jimmy since 1965."
