Weirdest? Hm... I got a charakter that i played for ... 1000 hours? Dunno. Got him since 5 years or so... So, he was pretty much invincible, did all the quests, had a Daedric Ruin full of loot worth ~10M Septims, and i thought "Well, would be fun to run trough Solstheim with an empty Inventory so i can carry more loot". You should have seen my face as i got killed by a Rieckling... So i got my equipment back, continued the slaughter, and first noticed that my Daedric Battle Axe was broken after five minutes because i swang it with such force...
Fetched a lot of books, made a pot of tea, turned the light off and lit some candles and spent the next five hours reading aforementioned ingame books... Happy times.
Started a new character yesterday and noticed that i have memories of literally every rock in Molag Amur (I spent the first 100 hours of my 1000-hour-character wandering the wastelands, collecting Trama Roots and Cliffracer Feathers, brewing levitation potions).
Dumbest? Everything above i guess
Got ill ingame and deleted that charakter because i couldn't get my attributes back.
Ran up to an Ordinator shouting "I'M WATCHING YOU TO, SCUM!!" at my Screen and got killed in one hit.
