Wel done!
Because anyone who's really paying attention is "in the know" about the correct name of the Messiah.
Armageddon: where experts are hit hardest.
Revelation 16:16 And he gathered them together into a place called in the Hebrew tongue Armageddon.
Which is prescient because the name Armageddon is analogous to Hill Valley, and Joseph was the Lord of Dreams.
'55, the time to welcome the bride [כלה] aka "a dream" (as per the Four Aces singing in Hill Valley 1955).
"The future is in your hands" in spite of the doubting Thomases out there.
Phinneous: ever notice that Sandeman Jerez is across from the Palace of Time?
Or run a search on "SANDEMANs NEW Jerusalem".

Re Mr. Sandman (Lord of Dreams) and the Four Aces:
>Sarge, I really do have a plan.
Oh, so now you have a plan. Well, let's hear your plan, Wally.
>What if the hovertank did work? That'd prove you haven't diverted the money.
Oh! That is so stup... What?
>That would prove you hadn't been diverting the money. Wouldn't it?
Are you saying you can get the hovertank to work?
>No, of course not. But we don't need to hold four aces if they think we hold 'em.

Dream on, it's the same as living in a movie!
It goes a long way in explaining why Joseph was quite the... irritant. :-D
