Empty Containers In the Refrigerator, Why?

I was looking in the refrigerator to fix breakfast, and I found the container of salsa below. For added effect, the photo is upside down, as was the salsa container. (Must add–it’s NOT because my husband was drunk and eating salsa and chips. He was perfectly sober last night, and I found it this morning):

I don’t understand why this was in the refrigerator. It’s empty. It’s dirty. The garbage can is right beside the refrigerator. In fact, putting it in the trash would have been EASIER, because then no need to even open a fridge door, just throw in trash.

Questions to guys: I just had a suspicion that this is not accidental. After so many reminders, why would he keep doing it? I am thinking there may be some type of thrill involved with this “empty things back in the fridge” thing. This HAS to be intentional, or at least serve some purpose. It just has to. These guesses may be way off, but let’s consider them a place to start. Could it be that:

1) When you insist on putting empty things in the fridge, it involves some type of trick you are playing? Kind of like: “I’m going to play a trick on people and make them think there’s salsa in here! They’ll never know the container is empty! hahahah!” ???

2) Putting empty things in the fridge stem from feelings of rebellion? I’m saying thoughts along the lines of: “I will show that biotch girlfriend of mine who’s in charge. I’ll put this d&^%# empty salsa container upside down in the fridge. That’ll show her to try to boss ME around.”

Anything of this nature? Sorry, if I seem really off target, it’s because I truly don’t get it. But I’m kind of interested in learning.
