Q: You'er presented with a smooth-faced, eight-foot-high wooden wall. Your objective? Get over it. To, like, save comrades or something. How to accomplish this?A: Take a running start, brace one foot against the wall, throw one hand to the top, try to hang on long enough for a comrade to either grab your hand at the top or for another comrade to push your butt up from below. It takes team work! over it.
