Wow this pangram was tough to get. Luckily, my sister (www.twitter.com/raablauren) came to my aid to reassure me that it is a word I know.
So after some time of frustration and some pretty gross and incorrect guesses, I finally got there.
Along the way, I got words like uncock, which is fine if you think of it in sense of a gun and not think of in the context of a not-so-surehanded mohel.
