Pangrams are sentences that contain all of the letters of the English alphabet. Perhaps the most famous pangram is "The quick brown fox jumps over the lazy dog." Here are some others:
1. John quickly extemporized five town bags.
2. Frowzy quacks vex, jump and blight.
3. Quack! glad zephyrs, wave my javelin box.
and probably my favorite:
4. Pack my box with five dozen liquor jugs.
Do you know any others?
