The party I'm DMing (group of a bard, a ranger, and a rogue) were near the end of a dungeon, searching for a rare ore. In the last large room, they come up on a wyrmling with a small horde of gold and the ore they're looking for in the walls.

With the dragon on the other side of the 100 foot room, the Ranger casts "pass without trace." He then sneaks around the corner and fires two arrows in its left eye, blinding the creature. The bard then plays his lute to draw out the little thing. As the wyrmling walks towards to the entrance, the party hides behind the wall. Dragon walks through the door and sprays fire, missing the party hidden to the left.

As it looks around, the rogue, with her own 10 stealth and another with the "pass without trace," she sneak attacks the dragon and takes out its other eye. It then retaliates spraying fire everywhere, almsot taking out the bard. The bard then backs off and heals himself while the other two party members make their way through the entrance.

The dragon backs into the room, scared and now blind. The rogue and ranger head over to the small piles of gold and start packing it into the ranger's bag of holding. The dragon backs itself into a corner, when it then heard something digging in its gold. The dragon starts toward the sound when the bard casts deafness on it. The blind and deaf animal rushes to it nearest pile of gold and starts digging in its gold, trying to comfort itself. The bard joins the party and helps fill the bag with gold.

After filling the bag with 500 pounds of gold, the party then turn to start mining the metal out of the walls. The bard and the rogue take their pickaxes and head to the walls. The ranger focuses on the dragon flying around and casts "hunter's mark" and then shot it twice with extra attack. He get's two nat 20's (double damage in my games) and with the extra damage from hunter's mark takes the dragon from 38 to 5 hp. The major damage makes him drop to the ground dealing the final 5 damage, killing the poor dragon.

EDIT: I posted this during the encounter and since then the ranger cut the head off the wyrmling and is getting armor made from it.

tl;dr My party is full of dragon abusers and are now on a "Do not let adopt" List.
