Cover art for In Corolla lyrics by Mountain Goats, The

It is servant, not serpent. Yes, there's reference earlier in the album to him being a snake to her Eve, but this is a prayer to God, not to her. Additionally, the final word here is them instead of you:

Here's hoping they have better luck than I had down here with them*

"Them" is referencing other people in general. Kind of a "hope they do better than I did," a half-assed prayer before "all that water rushing in" and the narrator drowns.

Today was the first I really heard all the lyrics and it is easily one of the most devastating songs I've heard.
