So, what's the symbology there?

Symbology? Now that Duffy's relinquished his "King Bonehead" crown, I see we have an heir to the throne. I'm sure the word you were looking for was "symbolism". What is the ssssymbolism there? Let me explain it to you. In Greek and Roman mythology, when you died, you would have to pay the toll to Charon, the boatman who ferried you across to the gates of judgment. This made sure the dead came to atone for what they did during their lives, Detective Dollypoposkallius.

Jesus, you're the first one that ever got that!

Yeah, well, I'm an expert in ... nameology!
