One 's' or two?

Scott: does it scare you that my MS Word knows how to spell "Barbara Streisand"?

Kim: ...

Kim: yes

Kim: a lot

Scott: I'm just waiting for the little paper clip guy to appear and say, "It looks like you're writing about Barbara Streisand. Would you like to hear me gush about Funny Girl?"

Kim: hahahaha

Kim: oh man

Kim: that would be so classic

Scott: right

Scott: or "Yentl is my favorite" or whatever
