I know I'm not the first to think of this . . .

but I was just listening to the Dropkick Murphys' "Skinhead on the MBTA" and thinking about the original "Charlie on the MTA."  If you're not familiar, the premise is that a guy named Charlie was able to board an MBTA train, but not able to get off, due to a fare increase.  Short just one nickel, he is fated to ride the train beneath Boston forever.

In the second stanza, these lines occur:

Charlie's wife goes down
To the Scollay Square station
Every day at quarter past two
And through the open window
She hands Charlie a sandwich

As the train comes rumblin' through. 

. . . .

WHY COULDN'T SHE BRING THE MAN A DAMN NICKEL???
