What do pig intestines and squid have in common

This is just funny. Ok it's also a little scary as I love Calamari!

"Calamari is on one side of the plate, sliced hog rectums are on the other. Which is which? We got a tip about a meat plant selling pig intestines as fake calamari, wondered if it could be true, and decided to investigate. Doppelgangers, doubles, evil twins and not-so-evil twins, this week. Fred Armisen co-hosts with Ira Glass." (from This American Life)
