-== Conundrum ==
-What happens when you run the following program:
-copy the line below twice, the first time without quotes.
-"copy the line below twice, the first time without quotes."
-==Answer?==
-ehehehehehe, so what is the answer!
-When you do as instructed, you get a repeat of the two lines as they are now. The first line without quotes becomes a new instruction. Your interpreter then executes it again and so you get a never-ending program! This is obviously in pseudo-code though.
