First Lady Laura Bush, wearing a savvy business suit, strolling in Texas amid patches of grass and twigs: normal.

First Lady Laura Bush strolling in Texas with the holy trinity, Jonas Brothers Joe, Nick and Kevin: sooooo not normal!

But it really happened, folks!

This fab foursome promoted the First Bloom conservation program by helping students to make seed balls from compost, clay, native grass seeds and water (talk about hands-on!) with the 150 young people who gathered at Dallas's Trinity River Audubon Center.

Mrs. Bush and the siblings Jonas also went on a hike in the Great Trinity Forest and learned to identify native plants and about the restoration of the area's native grass. The goal: to help the mostly city kids connect with Mother Nature and develop a deep commitment to conservation.

Gotta love those Bros -- they're constantly "doing something" to make a positive difference!
