Trying to be difficult

Why is the bag being taken out in the first place? You just need enough to open it.

Personally, I ask myself why you need the box...?
Most cereal I buy comes without a box anyways, but can't you just throw the box away, if it does?
- Easier to store in my cabinet alongside the other boxes
- The without a box thing is a german economic sphere thing.
- I agree. Like the box lasts for me from the point in time I leave the store to when I arrive at home. The bag too because I out in another container... But I guess that's not that common.
For standing in kitchen, looking around frantically and posing with the bag like it's the child animal from this Disney movie with the lions.

DO NOT take the full bag out of the box. You will regret it immediatly.

You just have to eat enough for it to slide back in easily again.
- But then it's just an empty bag.
  Or maybe I just can't control myself.

For some reason this is weirdly relatable even though I can't imagine a single scenario where I would have had to take the bag out of the cereal box

Just stuff the bag back in and then gently shake the box and it will go back to normal

Literally became big chungus

Same with pancake mix.

Are pancake mix even that useful, btw? Aren't pancakes the example of something quick and easy?
- Depends on how easy you need. There are pancake mixes that only require some water.
  This is a "simple" non-buttermilk recipe
  
  2 cups all purpose | plain flour, (290 g | 10 oz) 1/4 cup granulated sugar or sweetener, (60g | 2 oz) 4 teaspoons baking powder 1/4 teaspoon baking soda 1/2 teaspoon salt 1 3/4 cups milk, (440ml) 1/4 cup butter, (60g | 2 oz) 2 teaspoons pure vanilla extract 1 large egg
- Is measuring out 2 items easier than measuring out 10?
  It's useful, but not as good as scratch-made... especially the "just add water" varieties. But quick.
I've only ever seen pancake mix in either a re-sealable bag, or just a box; never a bag in a box.
- Bag in box is most common configuration in US.

Put it back with the box popping out. Shake it side to side until the box pops back in.

Then you had run advanced physics calculations just to put back inside the box.

I don't even know what this meme is trying to say

If you take the bag right out of the box it tends to be difficult to put back into the box, having seemingly become larger like the rabbit in the OP picture.
- Why are you taking the bag out though?
