Dumbest thing I did was that on the PC, messing around with consel comands, and tried to spawn a simple cow, but I got a dragon instead, a legendary dragon, how I don't know still to this day.

Fighting giants with very low level... :F

Fighting giants with very low level... :F

I remember doing that! The giant looked so small from a distance. Then it got closer and I realized how big it was. I was like "SHIT!!" Next thing I knew, I take on hit from his club and Im going to Secunda!

Also a very stupid thing I did once: Punching a child because he was rude... Big mistake... ;D Everyonce in whiterun started attacking me.

Tried to take on giants before I was at least level 15.

Talos, I was a noob

I was home alone for a weekend and spent the whole time playing Skyrim (obviously without pants required). I had a glitch with the "House of Horrors" quest in Markarth. Vigilant Tyranus and I entered the abandoned house, and the lights dimmed and the screen shook, just like it's supposed to for that quest. However, it glitched in that the front door, which was supposed to be locked, wasn't. Despite that, Tyranus kept shouting, "There's no way out! THERE'S NO WAY OUT!" 

Rather than completing the quest, I left the abandoned house through the unlocked door. The screen was still shaking and the lights were still dimmed everywhere. I couldn't see unless I used Night Eye.

So I spent two straight real-world days playing Skyrim with a weird graphical effect and a constantly shaking screen. Barely got anything done because it was impossible to play like that, but I was determined to do it!

Later fixed the glitch by killing Vigilant Tyranus. Molag Bal never told me to do it, I just got fed up with it and killed him of my own accord. The shaking and dim lights stopped, and Molag Bal thanked me for doing what he'd asked of me EVEN THOUGH HE HADN'T SAID A SINGLE WORD TO ME BEFORE.

Needless to say, after such a serious slight, I refused to do his bidding and complete the quest. From that day forth, Molag Bal was my least favorite deity ever. Of any religion. Screw that guy.

Basically, my friend Dylan and I started a new game, we got super bored with the intro, the cart part, at least, so I spawned in... A few... hundred werewolves. And Alduins. And Heimskrs. And we killed the cart driver, and the horse, then resurrected the horse, then killed the horse, and we turned the cart into an ultimate spinning meteor of death. We essentially destroyed the game, and had to restart. But it possibly caused one of the greatest laughs of my life.

I understand that there are a lot of players who tend to, well, "start off with a bang". That sounds like a lot of fun, though!

I never really took a liking to Molag Bal. He's just kinda... "Kill this dude. Bring me this other dude. Kill him. Beat him into submission. Here's a mace. Leave."

A friend of mine, on her first time playing, tried to walk to Whiterun after getting the quest to go to the Jarl, as you do. She checked her map, drew her longsword, then headed down the path. She didn't know what to look for so she followed the path without taking any turns off or hesitations along the way. Long story short, she ended up in Winterhold after about 2 hours.

Also, my first time playing, I tried to find the entrance to Whiterun and went all the around the North side of the hill and got about halfway to Rorikstead before realizing I was missing something.

First time playing tends to be the most confusing playthrough.
