If there's one thing-, If there's one thing,
If there's one thing-, -there's one thing-, -there's one thing-,
-there's one thing-, it's that I know nothing.
...
If there's one thing I know for sure-
...
If there's one thing I know for sure-
...
If there's one thing-, if ther-, if ther-, if ther-, if ther-, if ther-,
If there's one thing-, If there's one thing,
If there's one thing-, -there's one thing-, -there's one thing-,
-there's one thing-, it's that I know nothing.
...
If there's one thing I know for sure-."
