Typically in copyright when one work contains 0.0000033% of another work, we don't even raise fair use. Rather, we dismiss the use as *de minimis* (short for *de minimis non curat lex* or "The law does not concern itself with trifles"):

Busting someone who takes 0.0000033% of your work for copyright infringement is like swearing out a trespassing complaint against someone because the edge of their shoe touched one blade of grass on your lawn.
