Me-Maw is fiercely protective of her "Moonpie" and makes it clear she hasn't forgotten Amy breaking Sheldon’s heart during their breakup.
The episode title is a reference to a famous 1991 artwork by Damien Hirst—a tiger shark preserved in formaldehyde. It’s a classic Big Bang nod to high-concept art and science!
It takes some courage, but Amy finally tells Me-Maw that she loves Sheldon just as much as she does.
Meanwhile, Howard and Raj get into a heated (and hilarious) debate over whether a movie theater's "frozen" ice cream is actually better than regular ice cream.
