The thing is it uses like 30-something letters (I'm too lazy to count) and it uses the letter 'O' something like five times (too lazy, again).
If you're gonna make a sentence that uses every letter in the alphabet, then that sentence had better be 26 letters. Like this:
Q: When'd KFC's gravy blitz-jump ox?
Now, that's what I call efficient.
(PS: How can I be too lazy to count the letters in a sentence, but I can come up with a sentence using the entire alphabet?)
