Full Bars, a Halloween-themed episode of Bob's Burgers (airdate: 10/7/13), opened with kids wearing costumes at school. In the background, shown at least three times, was a boy dressed as an Indian chief.
Not a big deal, but not cool. Apparently Bob's Burgers didn't get the memo about stereotyping Indians.
