Anyone know the meaning of "Pull out the plug and wet him all over" and "put him in the long boat til he's sober" from the song "Drunken Sailor"? Should I assume that the long boat verse means put him in the lifeboat that's aboard ship in order to put him out of sight til he sobers up, or does it mean put him out to see in a lifeboat? I'm clueless about the "pull out, etc. verse.

Thanks in advance!
