Glorified G

I was bringing in groceries for my sister sometime last weekend, which included a six-pack of Propel lemon-flavored water, from the makers of Gatorade. I decided to make light of the purchase.

"You know how Gatorade changed their name on their bottle labels to G?"
"No, I didn't know that. I've seen the commercials, though."
"It's a good thing you bought some Propel before they did the same thing."
