Can't remember where I heard this. Two skiers are at the top of a mountain discussing the best route down. Skier 1: I know: we'll do a zig and then a zag. Skier 2: No, that's far too dangerous. We'll have to do a zag first and then a zig. Skier 1: I think we could get away with doing the zig first. Let's ask someone else. A third man arrives at the top of the mountain clad in full mountaineering safety gear, and the first skier turns to him: Skier 1: Do you think we can get away with doing a zig and then a zag here, or must wqe do a zag first, and then a zig? Third man: I don't know, I'm sorry. I'm a tobogganist. Skier 2: In that case, please can I have twenty Rothman's?
