Don't know if this counts as a bug... but in Wrath I used to drop http://www.wowhead.com/item=40536/explosive-decoy around low level horde zones, and killed several low level players when they went to kill it thinking it was a critter. This also worked in starting areas, eg you could kill people who were not flagged.
Still missing those days, where jumping out of lava in molten core resulted in druids staying in aquatic form. Nothing better than having 6-8 druids swimming around midair right in front of ragnaros![]()
The instant re-spawn of Whiptail herbs in Uldum.
Some that happened during my play time(Started in 3.0.8):
-Ensidia Saronite Bombs
-Retlol bug in 4.3 with Seals
-ADDINATIONAL INSTANCES CANNOT BE LAUNCHED haunted me for many weeks, missed out on 2 BHs on my main during Cata
-Powershot has a -90% miss chance by default. I was testing this on my friend in duel, he was SITTING still and I did like 5 Powershots, none hit the target(no miss/dodge/parry or nothing)
-4.0.1 in ICC as a Warlock, Destruction was OP as fuck, then 4.0.3 nerfed Destruction by a flat 18% lol
-Mage soloing a Quarter of Naxx with the spellsteal-able shield from a mob
-Yogg Saron +0 exploit with Warlocks using Drain Soul to not gain any Insanity
-Vashj'ir quests bugged at Cata launch, so many got fucked trying to get Server Firsts xD
-Super Wand during MoP beta, casters doing super damage with it lol
-Instance Servers crashing at MoP launch, my dung team got in while like 3 other teams were locked to Loading Screen bug
My favorite one was during Vanilla having a raid member get Living Bomb from Baron Geddon in MC and him getting warlock ported to the center of the IF AH back when it was the only AH so it was always extremely crowded. xD good times!
Also the instant repsawn rate of sheep critters in Uldum at the beginning of cata, me and a fellow guildy spent an hour and a half AOEing them to easily obtain the critter kill squad achieve and unlocked the armadillo pet way before it was even possible for someone to have enough rep to buy it.

There was an evil bug at start of cata in vash.
A fish you had to kill several of for a quest done a bite type debuff that done damage every 3 seconds, sadly the debuff didn't wear off.
So couldn't do anything except die.
"Additional instances cannot be launched"
Got to go for this one for the most annoying one.
