"I do believe in potatoes," Rincewind says fervently. "But these are huje! With a 'J'!" He holds his hand above his head to demonstrate. Er," he frowns, "that should have been ducks with fur. Sorry. And it's not like I made them up. On the Disc, you have to take what myths are offered."
"Yes, but I can run from that too, that's the beauty of it. And keep running." A simple philosophy, but it's kept him alive this long.
"It's not for the plate," Rincewind explains. "Well, actually it is. But I don't want to glue it back together."
I know! And probably caused a hole in the fabric of reality! And sorry about the furry duck thing. But I think that this actually works out in an odd Rincewind sort of way.
