How does the FBI use 'Portlandia'?

Recently it was revealed that IFC had renewed 'Portlandia' for two more seasons, which will be the show's fourth and fifth, respectively.

That news probably made an organization happy that you would not have thought would really care about a show on IFC, but surprisingly does.

You see, the Federal Bureau of Investigations uses the show as a teaching tool. According to Carrie Brownstein (who is the show's co-creator and co-star with 'Saturday Night Live' alum Fred Armisen), an instructor at the FBI Academy in Quantico, Va., contacted the producers of the series and asked for permission to use the sketch "Sanitation Twins" in its advanced-intelligence classes.

Here is the sketch:

"We granted permission, although he didn't tell us why he was interested," Brownstein said about the sketch, which focuses on recycling.

'Portlandia' has won a Peabody Award. Each of the new seasons will be 10 episodes in length (prior seasons featured 6, 10 and 11 episodes. Why the weird numbers, I have no idea).

Season 4 returns in early 2014, while season 5 follows it a year later.

In announcing the return of the show, IFC President and General Manager Jennifer Caserta praised its variety of topics.

"'Portlandia' has celebrated sustainable local agriculture, underemployment, avian crafting, gender politics, intense bicycle messengers and so much more," she said. "We can now celebrate two more seasons."

Why do you think the FBI wants that sketch?
