The Challenge - Season 14 Episode 3 -

Each team must "ram" an oversize log through a pair of 2-ton doors at the Castle of Good Hope that are locked with wooden planks on the other side. The logs have ropes attached to them, and players have to position themselves to where they can swing their log through the doors with the ropes, but without touching the logs. After "ramming" through the doors, the first team to retrieve their team flag wins.
