Since my beloved wife got a breast reduction we have a nightly ritual where I smear goop (anti-scar cream) on their incision lines. The first goop we had was from the surgeon's office and it was a silicone base that was pretty nice, but did have a tendency to build up a residue afterward. We asked the office about buying more and they pretty much said to get whatever as long as we were getting something on it. They also told us theirs was a "spendy" $50 which we didn't think was that bad.
So my wife bought a different product ($30) and we were both put out that it came in such a small tube for the price. We decided we'd use it up before going back and getting the first goop again, even if it was more expensive. We did like that the small tube didn't have any residue afterward, but for the price we paid it still seemed like a rip off.
The tube has appeared like it should be empty for weeks. Yet every night, we convene in the bathroom for nightly goop. I hold out my finger and my wife squeezes the tube. Every night, there is enough.
When we first thought it was almost done we bought another tube. Even if it didn't last as long we liked that there wasn't a residue with it. But now that the first one still isn't empty it's clearly very good bang for our buck, because it is frankly staggering both of us that we still keep getting more out of what appears to be an empty tube.
Early on I joked it was a Hanukkah miracle but at this point eight days was over last month and we're gonna have to make a new holiday to liken this phenomenon to because this is the energizer bunny of goop.
Every night now we wait with bated breath to see if this is finally the end of its supply. Every night, there is plenty. I told my wife it would be funny if I were secretly filling it a little bit to keep a long prank going but honestly the opening is so goddamn tiny that we couldn't possibly fill it on our own. We shall see when it's reign ends, but either way, we definitely got our money's worth.
