Thresh Pull Bug

I was playing a game as thresh, when my team and I caught the enemy Sion out of position. We were on Baron Nashor's side of the river, between the wraith's wall and the river wall http://i.imgur.com/UKzGLNX.png. I hooked the Sion, and right before he met his gruesome demise, my hook pulled him over the wall into the river bush.

Step 1. Place enemy champion by the wall opposite side of the river.

Step 2. Make sure that enemy champion is on course to be pull into NEXT TO the bush, but still on the other side of the wall.

Step 3. Have Thresh hook the enemy and pull them into the wall, on track to be next to the bush.

Step 4. If it plays out the same way it did for me, it should drag him on the other side of the wall.
