It occurs to me that Elwood and Billy look a bit like door-to-door evangelists in this page.  Except that the book Elwood has is probably not a Bible; it’s more likely to be a collection of racy logarithmic tables.

It’s not really too much of a coincidence that Ginger should accidentally run into Billy and Elwood like that, because they are after all looking for her.  But bumping into Creepy Guy Stone… okay, that was comedy.  Still, I’m sure you were all expecting it.
