I am sure it was not my first, but it is the only one I remember as being near the begining.
I was playing a Grey Elf (Multi-class Rogue/Mage). I had just joined my first group who had been playing a while. I was a few levels behind. we had come across a Deck of Many Things. Being very chaotic I decided to draw 3 cards.
First Card I drew got me a magic item (a +3 Long sword Defender). I was like WOW! This is great!
Next Card I drew was Death! Ack! I think I was level 5 multiclassed. So we were in the room where I was sitting and then rest of the party was there when Death showed up! There was no way I was going to hit it, so the Paladin of the group, jumped in to save my hide. In doing so the magic of the deck summoned another Death, so we had two to fight. I just ran around while he attacked them both.
With a bit of effort he was able to kill them. He yelled at my character (Stai) telling me how foolish it was to do that and that I should never to it again. I agreed.
As soon as he turned around, I drew my last card...
Boy was he pissed!
