This guys says he caught catfish out of the sewer (yuck!). Mike Iaconelli, the host of a new city fishing show on Nat Geo Wild, says he's been city fishing since he was a kid. His "fish story" includes catching everything from American eels to snakeheads to rats using bait like hot dogs and Philadelphia soft pretzels. Smells fishy, like a publicity stunt? Probably, "Fish My City" premieres today on Nat Geo Wild.
