Listen here, lil' buddy. The joke compares ancient Egyptians and JDM (Japanese Domestic Market) car fans because both groups "worship" something. Egyptians worshipped gods, and JDM car fans really like Datsun (Nissan) cars. See? It's funny 'cause it's like, unexpected, but also kinda makes sense. People like you probably drive a Prius or something.
