My pangram attempt so far:
Pacified zebra relished a quandry just like moving the white ox. (53 characters)
Which was a significant improvement on:
Quandries just like these very much delighted the ox who rescued the pacified zebra. (70 characters)
Ideally, I'd like to create one about 30 characters like: Sphinx of black quartz judge my vow.
All of this has nothing to do with the P22 (one of my favourite foundries, and the people who rebuilt the typeface for the London Underground) Pangram Contest.
