Falk's mother was an avid New York Knicks fan, a fact which influenced Falk's career decision upon his career path. Longtime childhood friend and colleague, Attorney Reid Kahn, remembers Falk proclaiming that he wanted to represent professional athletes in the fourth grade. Another high school friend noted that Falk was not good enough to make any of the teams at Douglas MacArthur High School (Levittown, New York), but that he was an ardent sports fan who frequently watched baseball games at Shea Stadium.
