I don't think this one has been answered yet. "Have two bananas" is from the Jungle Book (King Louie to Mowgli)

Here are some of my favourites:

1. "It is fate, but you can call it Italy if it pleases you, Vicar."

2. "Gordo? Gordo, I have to urinate."

3. "I'm happier than a tornado in a trailer park!"

4. "I know something you don't know! I am not left handed."
