That's funny. Mean, but funny.
Back to the post. If you know the tree you are cutting is going to hang up, find a better way. Hang ups occasionally happen and are never fun and always dangerous. They also are not done intentionally. It sounds like you want to preserve the other trees. If you yank out a hanger you will do a lot of damage to the other tree you are trying to save. Might as well do as SLOWP suggested and take out the tree in the way. Either that or have someone top the tree you want to cut down. Whatever you decide, be safe.
