Random questions for the universe

1. If there are 50 ways to leave your lover, and Paul Simon lists four ("Slip out the back, Jack"; "Make a new plan, Stan"; "Hop on the bus, Gus"; and "Drop off the key, Lee." Let's face it, "No need to be coy, Roy" is encouragement, not an actual way to leave one's lover), then what are the other 46? And is it merely 50, or is that just an arbitrary figure?

2. People say tornados sound like freight trains. Tornados, of course, predate freight trains. What did people say tornados sounded like before? Conestoga wagons? What about before that? Chariots?

3. What do you plant to get seedless grapes?

Just wondering.
