Admit it. Who else did this?

No... I think the DM actually placed the correct encounter in each room. But I do remember a little snafu when I first started playing. When each of us finally reached 2nd level our characters' experience totals were reduced to zero. It took a long time to reach 3rd level that way, but we eventually switched to the cumulative method.
It's a good thing the DM gave out a lot of XP back then.

We also did the 'giant rats' were big as vans thing.
My biggest goof was after running some of the earlier modules B1, B2, etc. and it was time to get some new ones I never noticed the AD&D labeling on them and ran them as they were but using rules from Basic and Expert sets.
It seemed very confusing for a long time

Way back in the day, whenever we entered a dungeon (and for a while, that's all that existed in the universe) we went room by room cleaning it out like we worked for Orkin or something. The idea that we retreat for tactical reasons, let alone skip rooms alltogether, was just utterly alien. We also did the whole "clean the dungeon by following the numbers" Ari mentions.

My favorite, however, was my friend Manuel, playing a Fighter (you know, back when that meant you were human) who carried a polearm +2. One day, in the treasure of a vanquished monster, he found a polearm +3 (magic items came with ID tags standard). Next game, when he attacks, he does so with a polearm +5. We all asked where had that come from? His answer, "Well, I had a polearm +2 and a polearm +3, so I put them together to have a polearm +5."

I'm still not sure how we decided it made sense, but the first time I ran BD&D I never had the monsters counter-attack.
The PC's just took turns beating the stuffing out of the monsters and taking their treasure.
It was like a dungeon full of pinata's!
After a few more reading of the rules, I realized that the monsters could fight back!

Hmmm, I guess I was lucky ... I learned to play by joining people who'd already figured out their errors. Which included such dandys as "paladins detect evil ... automaticly, on everything that comes withing 60 feet". Even if you were invisible, if you're evil, the paladin instantly knows there's something evil right over there.

The idea was to tease us: there are all these nice goodies, but you can't get them out, cuz you wouldn't know what/how to grasp them.

We went in with large sacks held open, and kept sorta 'vacuuming the whole room....

Oops.... oversight...

Lesson learned: don't assume you are smarter then your players. Just as there is such a thing as RBDM, there is also the RBPC!

I had a similar poor-foresight DM experience. He spent an entire evening devising a large (like 200 ft. square) treasure room which he fiendishly peppered with dozens of thoroughly detailed traps every few squares. He drew his own "map" on a sheet of grid paper with red numbers for each trapped square. He was so proud and smug that he actually flashed his map to us before we entered the room. A few moments later, when he described the room with its pile of glittering loot at the far end, he then asked us for our actions. I immediately stated that we were going to enter, walk to the left for 60 ft, turn 90º to the right and cross 200 ft. to the far wall and then follow the wall back to the right to the pile of treasure. The DM giddily looked at his map to see which trap we'd stumble into first only to realize that I'd described a clear path through the room. A little frustrated, the DM then said that I was cheating and that we should do it differently. I said okay and then told him that my wizard was going to dimension door to the pile of loot and throw it into my portable hole. My DM getting more frustrated that his wonderfully trapped room was being defeated so easily told me to do something else. I told him I would cast telekinesis and float the loot back to us at the door, or cast teleport to reach the loot, or cast fly to float over all the floor traps or summon monsters to set off all the traps, ect... He got so frustrated IIRC that he just ended the session then and there and we never did get the loot.

I remember cleaning out the Keep on the Borderlands...
the keep, not the caves.
I was 8 at the time, but I figured that since it was the name of the adventure, it must be an evil place and should be rid of everyone.

In my first Basic D&D game, my brother the DM thought a magic missile was a physical object. My elf character wound up carrying a magic bazooka, and the missile's explosion tended to kill a room full of monsters all at once.

ROTFLMAO!
