I couldn't understand the mechanism of a sentence from the book Born to Run by Christopher McDougall:
when it comes to grabbing a spotlight and persuading people to do things they’d rather not, Fisher could put a televangelist to shame (well, as much as that’s possible). Take this classic Fish tale that Krakauer tells about a rafting trip Fisher made into the Copper Canyons in the mid-1980s.
My problem is with the second sentence
Take this classic.... I can't understand the usage of the verb "take" at the beginning and so the rest of the sentence confuses me.
