tabard

Name: Tabard of Laos Flipor
Type: Tabard
Armor: NA
Abilities:

It's a tabard with stats! +10 Strength, +10 Agility, +10 Stamina, +10 Intellect,, and +10 Spirit (kind of like The 1 Ring, but ten times better!)
You may not think +10 is much of a bonus, but +10 Intellect means an extra 150 mana. And +10 Agility actually grants a whopping +20 Armor. Added up, these all mean a lot, and the fact that they're on a tabard makes them just icing on the cake.
Laos Flipor, if you weren't already aware, is a little-known lore figure-- she used to be a jester in the Court of Lordaeron. She was known for telling bad jokes, and apparently she told one too many and got Arthas angry at her. Right after he murdered Dad in WC III, he offed her, too.
How to Get It: If you've ever done the CLUCK! quest in Westfall, you'll be able to do this one. You can get the tabard from (where else?) the guild tabard vendor in every capital city. But they won't offer it to you unless you can prove, like Laos, how funny you are. So just go up to a guild tabard vendor, target them, and do the /silly emote 200 times.

200 jokes later, a ? will pop up above the tabard vendor's head, and this baby is yours.
