"And what exactly do your mother's words of wisdom have to do with this situation?" Gundar shrugged. "It looks like a channel. It's the right place for a channel. If I were digging one, this is where I'd dig a channel. So. . ." "So it's probably the channel?" Selethen said. Gundar grinned at him. "Either that or it's a duck.”
“You ever hear that expression 'If it looks like a duck and it quacks like a duck, it's probably a duck'?”
“If it looks like a duck and quacks likes a duck, it's a duck, right?”
“If it looks like a duck, quacks like a duck, it's a duck!”
“if it looks like ahh duck and Quack like ahh duck then....its an afflack!”
“If it walks like a duck, quacks like a duck, and looks like a duck, it is a very unfortunate situation for the batting team. On the other side of the image, although being definitely unfortunatable for the batting team, it is most definitely a glorious silver lining for the bowling team.”
