an easy one....
A man walks down a every long road in Ireland. This road goes in a straight line. There are ten pubs along down this five-mile road. The man walks all the five miles of the road without walking by any of the ten pubs. How can this be?
There's no earthly way of knowing which direction we are going. There's no knowing where we're rowing or which way the river's flowing. Is it raining? Is it snowing? Is a hurricane a-blowing? Not a speck of light is showing, so the danger must be growing. Are the fires of hell a-glowing? Is the grisly reaper mowing? Yes, the danger must be growing 'cause the rowers keep on rowing, and they're certainly not showing any signs that they are slowing. AAAGGHHH!!!
