I wanted to write Jack’s dialogue to match the exclamation Dr. Muffet utters when he bursts out of the lab. I knew the good doctor was going to shout “Eureka!” but was stumped for Jack’s utterance… until I looked up the origin of “eureka” online. Though it is from Greek origins, I found the link to the gold rush more popular and chose that instead. Been a while since I did some research for a word or story bit. Good times:)
