A man comes into his bedroom one evening with a sheep under his arm and says to his wife, "Look darling, this is the pig I have to sleep with whenever you hace a headache."
His wife replies, "I think if you'll look closely, you'll find it's a sheep."
To which he retorts, "I think if YOU look closely, you'll find I was TALKING to the sheep..."
That is the end of the joke but apparently I need to submit at least 500 characters so this postscript is both superfluous and redundant. On that note, in the previous sentence, I used the words 'superfluous' and 'redundant'. In this example, one of those words is superfluous, and the other is redundant. Work it out and get back to me... ;)
