Someone linked these in raid and I had to laugh because some were so funny! Here are my faves (and get ready to groan!)
Why does the best raiding guild smell so bad?
Because they never wipe.
How do you know someone's been playing since Vanilla?
Don't worry they'll tell you.
How does Naxxrammas fly?
With its four wings.
Why didn't the warrior cross the road?
No path available.
What are the chances we've gotten the last patch before the next expansion?
What is a rogue's favourite drink?
Why is Cenarian Circle neutral?
Because a circle has no sides.
Why can't Warrior tanks have children?
Because they use Protection.
Why didn't the rogue like his daggers?
He wasn't a fan of knives.
