ORLANDO, Fla. -- Add another dance move to Michelle Obama's repertoire.

The first lady gave "the platypus walk" a try on Saturday during a visit to Disney World's ESPN Wide World of Sports Complex.

The dance was inspired by Disney's "Phineas and Ferb" show, whose characters include Perry the Platypus.

It required some flapping of flippers, or arms if you're human, shuffling left and right and yanking limbs up and down, all to a pulsing rock beat.

Obama did the dance at an event marking the second anniversary of her "Let's Move" campaign against childhood obesity.

There goes that Saul Alinsky guy again

Newt Gingrich has taken to referring to the Saul Alinsky radicalism of the Barack Obama administration on the campaign trail.

The Wall Street Journal reported last month that former House Republican Majority Leader Dick Armey reportedly gives copies of Alinsky's book "Rules for Radicals" to tea party leaders.
