Ended up managing to entirely skip a puzzle by going completely out of the DM's wildest expectations for the scene

So, my group and I were in a dungeon, with a seemingly magically locked door, which wouldn't open despite our best efforts to unlock it. There was some kind of force pushing the door back whenever we tried to open it. We tried pushing the door and the more members pushed it, the closer we've got from fully opening it, and the DM kept saying it needed more strength, but at some point, the DM asked us to roll perception and two of the party members passed it, to hear someone laughing inside the door's key hole.

Our warlock decided to eldritch blast the keyhole, which got his finger bitten, cancelling the cast. Then, he took some distance before launching the spell again, which caused the door to briefly open to pass the bolt through, then closing again. It wouldn't open for us. Since the keyhole bit the warlock, I, the party's path of the giant barbarian, had an idea that there was something, or someone going on with the door, so I decided to do something about it.

I asked everyone to stand back, and everyone got ready for me to rage, or destroy the door, but the path of the giant gives me thaumaturgy, which allows me to do some magical effects, including, but not limited to opening unlocked doors and windows.

I've used it to triple my voice, then shouted at the keyhole. The door trembled with the noise and opened itself. The entire table was in disbelief, but most of all, the DM couldn't believe that a puzzle as simple as "everyone has to push the door" ended up brewing into a 5 minute madness, culminating with a 2.5m tall Hulking dragonborn just shouting at a keyhole. By then, he just gave up and let us in. Do you all have stories about a seemingly simple task getting extremely convoluted and ending up with wholly unexpected results?
