I think the newer Star Wars Battlefront games did that.

“I got fat because I ate too much.”

I could see Norm making a joke similar to this, but Id imagine he’d add onto the end by saying something after a pause, when the audience is visibly confused, like “Because I was getting fat. I was eating too much.”

Theres a good chance that the tag was supposed to be replaced when the price went up, and then this “sale” started sometime after, dropping it to the old price point. I would see it most often in the health and beauty sections of my old store, because they have so many small tags, sometimes the employee whos changing the tag cant find a specific one that needs changing and just tosses the new tag instead of working to find it.
