Cramer retires "They know nothing" button for Burnett

“Mad Money” host Jim Cramer said on the air Friday that he is retiring the “They Know Nothing” button that he uses in honor of CNBC anchor Erin Burnett‘s departure from the business news network.

Michelle Fox of CNBC.com writes, “Burnett thanked the ‘Mad Money’ host for being ‘the best, the greatest, the supporter, the proponent, the funny man, the crazy one, the mad one.’ She called her segments with Cramer the highlight of her day. Cramer, in turn, told Burnett that he was retiring his ‘they know nothing’ button in honor of one of their best moments together.

“Cramer, who teared up several times during the exchange, said the ‘best three minutes’ he has ever done on television was a segment he did with Burnett out of Petra, Jordan.

“‘Your foreign correspondent work is some of the best I’ve ever seen,’ he told Burnett, ‘You are a consummate professional.’

“With that, Burnett thanked her colleagues, friends and the viewers for ‘the best 5 ½ years of my life so far’ and signed off CNBC for the last time.”
