Hopefully his daughters aren't watching; President Obama just broke his own rule!
"You don't put stuff on your head if you're president," Obama once famously said when offered a football helmet, but apparently he's willing to bend the rules for a pretty tiara.
In fairness to the president, these adorable Girl Scouts must be impossible to resist. The troop from Tulsa, Ohio exhibited a flood-proof Lego bridge project at the annual White House Science Fair, according to Pete Souza, chief official White House photographer.
Souza loves the image so much, he's considering breaking one of his own rules and adding the posed picture into his 2014 Year in Photos.
