Walk Like an Egyptian

Andrew read a book about ancient Egypt yesterday and was talking about it with Ryan.  Andrew asked if he knew that the Nile river was really long.  Ryan said, "Yeah, it's over 300 feet long."  I heard this and said, "You know, 300 feet is only as long as a football field.  I bet it's longer than that."  He was quick to reply, "Well, I said it is OVER 300 feet."
