JOKE-OGRAPHY:
1. "Annunciation" (announcing something) and "enunciation" (pronouncing something) are two words that sound very similar, so I took the Biblical Annunciation (when the angel Gabriel announced Christ's birth to Mary) and set it beside an imagining of Jesus pronouncing -- or enunciating -- His first word. I alluded to this pun a couple weeks ago in a previous cartoon's description, then decided it ought to have its own comic.
2. My sisters suggested "Abba" as Jesus's first word. I thought it was perfect, because it's a plausible first word for a baby, since it's made up of simple syllables -- like "mama" or "dada" -- but it's also got that Son-of-God vibe to it.
