Easy Weapon Skill
This works for classes with pets. When doing the quest A Dire Situation you will get a powder to use on wolves. The powder shrinks the wolves and makes them non agro. The trick to this is to have a pet fighting the wolf while you are throwing the dust. The wolf will go non agro and you can work your weapon skill easily.
Despawn Guardian of Icecrown
These are the adds that Kel'thuzad spawns in Naxxramas. To despawn them, just get agro and pull them onto KT's throne. If they go through the middle they will despawn.
Just sacrifice your ghoul and it will take stealthers out of stealth.

This may only work with the DK flying mount. Go to Storm Peaks(K3) to buy a certificate to fly to Northrend. Now, get the loaned wind rider reins from Max right by where you get the certificate. Use the loaned wind rider reins and then mount your flying mount. You will now be on two mounts. Now, if you right click on the reins both mounts will leave and you will be flying.
