This fellow is former South Dakota state Rep. Ted Klaudt, who was just sentenced to 44 years for doing terrible things* to his foster daughters. The story is here.

Here's the scene as he's led in to prison with the other new cons:

[gates rumble open; the new cons file in]

INMATES: FISH! FRESH FISH! HERE FISHY FISHY!

[Klaudt enters]

INMATES: ...WHALE! FRESH WHALE! HERE WHALEY WHALEY!

*I phrased this euphemistically purely to avoid the wrong type of people coming to my blog from Google, not to minimize what this scumbag did.
