Fish Bait

From Wikipedia:

When used as a snack food, chunks of cured pork skins are deep-fried and puffed into light, irregular curls, and often seasoned with chili pepper or barbecue flavouring.

Microwavable pork rinds are sold which are microwaved in bags that resemble microwave popcorn (although not exhibiting the 'popping' sound) and can be eaten still warm. Pickled pork rinds, on the other hand, are often enjoyed refrigerated and cold. Unlike the crisp and fluffy texture of fried pork rinds, pickled pork rinds are very rich and buttery, much like foie gras. Unfried pork rind is also processed into colorful and appealing shapes for use as fish bait.

But it gets worse...

Sometimes the fine layer of hair is removed from the skin by burning; however this is not completely effective and some pieces still have the hair attached.
