Apparently, time travel has rules. For example, you cannot go back and simply take
something from the past—it must be given to you. Thus, our man from the future must
talk young Oliver Wilson Knight and his girlfriend into giving up the 1990 almanac that they
bought in 1950.
If there was such a thing as a 1990 almanac, and if it was in that package, wild horses
couldn’t get it away from me.
