Here are some of our favorite facts and stories of what life is like inside the White House:

In order to cut costs and save on manpower during WWI, President Woodrow Wilson kept a flock of 48 sheep to maintain the White House lawn. According to the White House, wool was auctioned off and $52,823 was donated to the Red Cross.

During WWII blackout curtains were placed over the windows of the White House, antiaircraft guns installed on the roof, gas masks hung from their straps on furniture, and the gates to the home were closed, according to author C. Brian Kelly of "Best Little Stories from the White House."

According to author William Seale, White House engineers asked President Roosevelt if they could change the color of the home by painting it in the "military camouflage style."

In 1970, Elvis Presley showed up at the White House gates and asked to meet President Nixon. The Secret Service showed "the king" in and the president was thrilled to meet him in the Oval Office.

The Nixons didn't finish moving out of the White House in time and thus President Ford had to serve part of his term from his personal home.

President Ford was once locked out of the White House in his robe and slippers in the wee hours of the morning after taking his dog Liberty outside to do her business. Since every door was locked, President Ford began to pound on the walls.

"The White House sprang alive, lights came on everywhere, and the Secret Service rushed to the scene to let the president back into his own house," Kelly writes.

Secret Service agents are responsible for the keys to the White House but due to several security breaches, the exterior doors automatically lock.

The West Wing was meant to be temporary, but President Taft didn't like the idea of walking to another building to go to work. The West Wing is home to the Oval Office and the Situation Room.

According to former White House Deputy Director Natasha Neely, the West Wing has radiation detectors. During a tour, Neely was informed by Secret Service agents that someone in her group brought in a form of radiation and nobody could proceed until the source was identified.

Insiders have a different name for the "Situation Room," they call it "Woodshed."

The exterior of the White House requires 570 gallons of Sherwin Williams' "Whisper White."

The Secret Service has a code for when the president and first lady are spending "alone time" together. Agents refer to this private time as "the couple is discussing the Bosnian problem."

All food headed to the White House is screened at a separate off-site location first. If guests were to bring food into the White House the Secret Service would dispose of it immediately.

Luxurious State Dinners are funded by taxpayers but at the end of every month the first family is billed for all of their groceries, toiletries, and dry cleaning.
