Groaking
This word means to watch people eat, in the hope they will offer you some. Now I know dogs do this all the time, but do humans do this aswell, I suspect they do.
Coca-Cola
Only 2 people on Earth know the secret recipe. Ones called Coca and the other Cola. I wonder if these two people know each other and they meet up to talk. Or the secret is so tightly held, its like The Da Vinci Code, with Doctor Robert Langford, except the secrets held by Doctor Pepper.
Coca-Cola was also originally green!
Snake
It takes 50 hours for a snake to digest a frog. Whats the matter you got a frog in your throat? You sound a bit croaky!
Apples
God was obviously right to warn Adam off apples, the actual pips contain cyonide!
Intelligence
Clever people have more zinc and copper in their hair. I always thought that was dandruff...
