Jason La Canfora works for CBS Sports as the “NFL Insider” for the network’s pre-game show, The NFL Today. Last night, while listening to a song by The Libertines, he tweeted “Arbeit Macht Frei.” The German phrase, which means “work makes you free,” is the title of The Libertines’ song but is best known for having been placed over the entrances to numerous Nazi concentration camps during World War II.

After being informed of his mistake, La Canfora apologized and deleted the tweet.

Hey, it happens.
