My oulipo pangram:
Microwaving flapjacks in a handy quartz box.
That's XXXVII symbols which I don't think is too bad, but can anybody approach XXV?
@plutoman took an hour to construct My Just King Schwartzkopf XLV's Bisquick Dough but that's XXXIX...! I am no good at pangrams.
@jamspank Good on you for having a go! I don't know about validity of pangrams containing Roman symbols! Schwartzkopf is a brilliant word for pangrams though.
