Anyone who works in sales knows you must be creative.

There is a 9-year-old in Denville who understands this concept when she sells Girl Scout cookies.

Last year, Lily Testa channeled Frank Sinatra by singing “New York, New York” but changing the lyrics to address the fact she is selling cookies.

This all started two years ago when she sang a Taylor Swift song.

At last check, she has sold more than 300 boxes of cookies.
