March 30, 2009 - April 2, 2009

Storrs, Chapel Hill, Detroit, Pittsburgh, Philadelphia, East Lansing, and Louisville. This was still March Madness, but with different cities for this two weeks' worth of episodes.

March 9, 2009 - March 12, 2009

Morehead, Cedar Falls, Johnson City, Radford, Ithaca, and Queens. It's March Madness again.

March 2, 2009 - March 5, 2009

Lambipati, Lion-Sur-Mer, Lioni, Lionsville, Lambs Corner, and Lamborn. Lambs and lions? Biblical references? Pretty odd for the Daily Show.

EDIT: As Rich pointed out, this is also a weather-related saying about March.
