These goats were set loose in the Congressional Cemetery

This is the Congressional Cemetery in southeast Washington, D.C.

About 200 former members of Congress and their family members are memorialized here.

Lots of famous people are buried here, too, such as J. Edgar Hoover, the first director of the FBI.

And Mary Ann Hall, the madam of D.C. who ran a bordello for Civil War soldiers.

A few months ago, it was discovered that the cemetery had some extra property. But the property is covered with thick poisonous plants that can suffocate the trees. Boo!

Clearing the land with machinery and pesticides would have cost more than $10,000 and harmed the environment. So the cemetery settled on something better: Goats!

Goats can eat poisonous plants and can clear an entire acre in only a few days. The cemetery ordered about 60 to eat for a full week.

A company called Eco-Goats brought the goats from Maryland.

A giant truck arrived Wednesday with a haul of goats. Yahoo News hopped on for the ride.

The truck backed into the cemetery, and off the goats went!

The goats began eating everything in sight.

Extra points for this guy.

Wait, you can't seriously be taking a break already. Your only job is to eat. Your. Only. Job.

Goats are pretty much gluttons. "It just amazes me, the sheer volume of vegetation that can go through a goat in a short amount of time," said Brian Knox, who raises the animals. "You're looking at 10 to 15 pounds per animal, per day."

After a week, the goats will clear 1.6 acres of land at a cost of only 25 cents per goat per hour.

Pretty sweet deal, huh?
