Noodling

Here in Oklahoma, we have fishermen who like to catch catfish using nothing more than their bare hands.

Dogging, stumping, graveling, hogging, tickling -- the practice goes by many names.

Here in Oklahoma, they call it noodling.

Wikipedia has a pretty good description.
"To begin, a noodler goes underwater to depths ranging from only a few feet to up to twenty feet. Placing his hand inside a discovered catfish hole, a noodler uses his arm as bait to entice the fish. If all goes as planned, the catfish will swim forward and latch onto the fisherman's hand and arm."
According to Wikipedia, the origin of the term noodling, is the word noodle, which is slang for a foolish person.

Seems about right to me.

P.S. - I don't think these Thai fellas caught their catfish with their bare hands, do you?
