ANSWERS

Ok, you guys and gals, you've had more than enough time to find the answers to the riddles; so, here we go:

1. Five eyes and a why - INVINCIBILITY (5 "I"'s AND A "Y")

2. Five vowels joined together in one word - This is what "askoxford.com" says

"We know of only one word in anything like standard use which has five consecutive vowels, and that is Rousseauian 'pertaining to Rousseau or his views on religion, politics, education, etc.' Apart from this, and the large vowel clusters in queueing, there are only the Greek-derived words of the pharmacopoeia type.

3. What did the big chimney say to the little chimney? - "You smoke too much!"

*******************

While we're on the subject, here are some more pearls of the English language:

- OOLOOPOOLOO - A palindrome (A word that reads the same in both directions). This one refers to a dialect spoken in Australia. I'm not sure you can call it "English", though!

- EDUCATION - A word containing all five vowels.

- ABSTEMIOUS - A word containing all five vowels IN THE RIGHT ORDER!
