That's Sam Kass, above, White House chef to the Obamas and Senior Policy Advisor for Healthy Food Initiatives, chomping on a SweeTango apple that Mayor R.T. Rybak, moments before, had given him in Chicago Tuesday, where they were both attending an urban food conference. The SweeTango was developed at the University of Minnesota and, apparently, the mayor just happened to have one with him (though we suspect he may have had marketing on his mind).

The mayor had also used the SweeTango in a friendly wager with his counterpart in Phoenix during the WNBA playoffs. (No SweeTangos were sent, since the Lynx won.)
