I did a little searching (almost wrote Googling but you know they don't want us to do that anymore right?) and found the Pyranna. I ordered one on the spot (only $12.95) and it arrived yesterday. As you can see from the photo, it is packed in exactly the kind of packaging it was designed to open. At first, I was amused at the irony of it all. Then I read the line: "Safely and easily opens packages like this one".
I think there was a real opportunity missed here. It would have been far more effective to have packed the Pyranna in almost the same way but with an easy and safe way to open the plastic once the joke was played. Or, they could have included a cheap trinket (stickers or something else both silly and potentially viral) in a welded package that could have been the first Pyranna victim.
My kids and I are still chuckling over this one. I'm almost inclined to leave the package unopened and hang it on my office wall.
