"I try," Rincewind says humbly. "Wait! What?! I didn't point at anything. You pointed me. Er, had me point. Um, as an example. No real pointing. No real tiger. And what else are you supposed to do whilst running?"
"OW! OW! OW! That only goes so far you know!" He reminds Xellos in a yelp. "I know," he says, humble again.
"It was an accident!" Rincewind almost howls. "It's not as if I'm the only person who ever broke crockery you know!" Rincewind can't help but look at his feet to see if they've been changed into hooves. Stranger things have happened. Speaking of talking (sorry), Rincewind has slowed to barely more than a trot at this point. "It sounds like you expect me to need to know how to run like this," he comments, his heart sinking.
