"The quick brown fox jumped over the lazy dog."
because it contains all the letters of the alphabet.
I like him because he wants to make life easier for people and said a shorter sentence to use is
"Pack my box with five dozen liquor jugs."
which I think sounds much better.
But I must also cite him for lying because
"The quick brown fox jumped over the lazy dog."
doesn't contain every letter of the alphabet - its missing a "s".
