Sort of an updated version of "Billboard Frolics", Friz Freleng's eye-popping "Lights Fantastic" depicts a bunch of billboards - apparently around Times Square - putting on various skits. This cartoon really shows off Freleng's penchant for synchronizing music and action (especially with the conga beat). Freleng also made ample use of this in "Pigs in a Polka" and "Show Biz Bugs".
Mostly this was a place holder in 1942. By that point, Bugs Bunny was the undisputed Warner Bros. cartoon star, Chuck Jones had totally eschewed cuteness in favor of slapstick, and the United States' entry into WWII prompted a series of cartoons portraying the characters battling Nazis. But this was certainly a good place holder. Very similar to "Billboard Frolics", true, but I recommend it.
