Hello, this is my first post here ever so be nice.
Okay, I got bored one day and started looking around AH in Ironforge. I tried to get over the "Auctioneer Lympkin" Auctioneer Lympkin - NPCs - World of Warcraft.
I found one way. Here we have the Screenshots.
1. Go to the Auction house in Ironforge

2. Get to the wheelbarow and jump up as you can see on the picture.

3. Now jump on the Weapon rack.

4. Now jump on the Invisible floor over the Auctioneer.

5. Now you can /point at everyone under you.
Short summary:
1. Jump on the Wheelbarrow.
2. Jump to the Weapon rack.
3. Jump over the auctioneer to the Invisible floor.
4.Grats.
Done with my first post. FLAME ME !
