They Might Be Giants contributed a hidden track to the recently
released Liars, Sissies and Fiascoes: The Best of "This American
Life." The two-disc set collects stories and essays from the National
Public Radio program, which is in the same quirky vein as They Might Be
Giants' music. TMBG's cut, "I'm Sick," is credited as a proposed theme
song for the show.
