Billy McGuinty's Ghost

[Keith]

and that was the night Virgin Mary wept blood.

that's the punchline, but i failed to get it.
there's the allusion to virgin mary statues weeping blood, but the only connection i can think of between that an a pub, is a pun on 'bloody mary'. however, that makes sense only if the pub were serving virgin marys earlier...which they would never have done.

Hi Ronsaik
The premise of the poem is that he wants to get his punters back so his next new scam is one that will get people coming from miles around to see, I guess its not much of a punch line if it needs explaining, Now what can I get you to drink
