The quick brown fox jumps over the lazy dog.

A simple sentence that contains every letter in the english alphabet. Who cares? Well ... credit this to my dad ... I learned this phrase when I would tag along with my dad and watch him perform tests on Western Union teletype machines that used physical motion to type letters. You know, like the "old" typewriters. This simple sentence would allow one to check every letter to make sure that they were all working ... so simple, yet so cool.
