(WASHINGTON) -- Want to drive the president crazy? Just show him a bowl of guacamole he can't eat.
Obama "lose[s] his mind" over chips and guac, he told guests at the annual Kids' State Dinner Friday.
The dinner (technically a lunch, Obama pointed out) honors the 54 kid winners of the first lady's "Healthy Lunchtime Challenge" recipe contest.
But the rather than focusing on nutrition, a particularly chipper Obama went a little off-script, instead divulging the first family's junk food soft spots.
"One thing – maybe I shouldn't say this – but it's not like our family, including me, don't have, you know, some snacks once in a while that may not be, you know, on the perfect nutrition chart," the president said.
Sixteen-year-old Malia's weakness is ice cream, and 13-year-old Sasha's is sushi (and pie), he said.
"The first lady? French fries," the president revealed — prompting her to publicly swear off fries.
