I like the idea, but unless I'm missing something shouldn't the theme answers NOT have the "if" "and" "or" "but"? The theme reveler indicates there wouldn't be those letters in the answers. I would come up with good stand alone answers that have the "if" "and" etc removed. I think it would also be cool if you removed those words in the order of the phrase--i.e. take out "if" first.
In short, I like the theme idea, but the answers need to be reworked.
Hope this helps.
