"The Five Boxing Wizards Jump Quickly"
This is much better than "the quick brown fox jumps over a lazy dog", which was the only other pangram I had known before seeing this blog entry by X guru Keith Packard. Talking of X, XFree86 released their server version 4.5.0 almost a week ago and I haven't seen references to it on any of the main nerds news sites yet. From the same blog entry by Keith, I came to know that a font designed 530 years ago still looks quite decent.
