Cena and i were on a team with Lynsey for Cranium last night.  We won $25 each as the top prize after we tipped Tiffany for putting it together and running it.  One of the questions was a definition with multiple choices and i knew the answer before looking at the options.  Crepuscular.  I know it because of wildlife biology class at Finger Lakes Community College.  I learned it because it describes animals that are active at dawn and dusk — they are not nocturnal or diurnal but crepuscular.
