Last night's excellent episode of NBC's "Parks and Recreation" centered around Leslie Knope's efforts to put together the city's summer catalog for the Pawnee Parks Department.

Here's that catalog.

You can read about all the featured classes, including "Get Digital" (learn DOS and Lycos!) and "Raccoon Trapping" (never again fear raccoon attacks!).

But the staff bio section is the best. Did you know that April (featured on the cover) was born in Bjork's house in Iceland and enjoys reading "Family Circus" and traveling through time? She's also in charge of the bio section of the catalog, and no one checks over her work. 

...She is at the very least a heckuva good sport.
