Happy Birthday to Me!

MANDY:

So, you're astrologers, are you? Well, what is he then?

WISE MAN #2:

Hmm?

MANDY:

What star sign is he?

WISE MAN #2:

Uh, Capricorn.

MANDY:

Uhh, Capricorn, eh? What are they like?

WISE MAN #2:

Ooh, but... he is the son of God, our Messiah.

WISE MAN #1:

King of the Jews.

MANDY:

And that's Capricorn, is it?

WISE MAN #2:

Uh, no, no, no. That's just him.
