Lots of interesting theories none of which may be true. Of course we will never know.
My theory is that TW and RM had actually seen the questions beforehand, and that RMs off camera initial response might have highly libellous, and distinctly insulting, about Faldo, and might even have included a few expletives. That, for me, would explain Tiger's fit of the giggles, and makes Rory's self control even more admirable. Pure speculation on my part obviously.
