Quote - "Sure, sure. It's obvious, no?"

A phrase Mr Griffs uses when listening to something he doesn't want hear or when he doesn't want to admit his lack of knowledge about something. We often use this line to show his quirky idiosyncrasies and to highlight just how much of a unique character he is. | As he was munching on a grape, the worker behind the station started to spruik the product. He had just begun to rant on about the antioxidants in red grapes when Mr Griffs cut into the conversation. ‘Sure, sure. It’s obvious, no?’ He had long ago stopped listening to pushy salespeople and often used this phrase to pacify them. |
