No worries! It can take up to 24 hours for an egg to be fertilized. From there the embryo needs about a week to work from the ovary through the fallopian tube and get to the uterus.
The term thagomizer was coined by Gary Larson in humor, in a 1982 Far Side comic, in which a group of cavemen in a faux-modern lecture hall are taught by their caveman professor that the spikes on a stegosaur's tail are so named after the late Thag Simmons.
Sci-Fi writer Robert A. Heinlein first used the term moonbat in his short story Space Jockey. I agree with westsideguy, moonbat is appropriately named if he/she thinks bringing in someone inexperienced to be the CFO of a bank is a good idea. You could always toss in moonbat for effect though.
