Amusing story. See if you can figure it out.
I was at the Walgreen’s getting some batteries for my watches. The total for the purchase was $21.12. The cashier made a brief comment about that being an awesome number.
It took a moment for me to respond, even though I immediately understood her reference. When I did, she said she was wondering if I would get it, and I told her it was taking my brain a second because I was having PIN confusion.
She then proceeded to make a joke about Hemispheres working together. Took a second to get that one, walked back, gave her a thumbs up.
Anyone get the references, or am I just old rock?
If you guessed “Rush”, 
One of my favorite Rush songs. Especially live.
