input: United States Postal Service

The USPS is often mistaken for a government-owned corporation (e.g., Amtrak) because it operates much like a business. It is, however, an ''establishment of the executive branch of the Government of the United States'', (39 U.S.C. 201) as it is controlled by Presidential appointees and the Postmaster General. As a government agency, it has many special privileges, including sovereign immunity, eminent domain powers, powers to negotiate postal treaties with foreign nations, and an exclusive legal right to deliver first-class and third-class mail. Indeed, in 2004, the U.S. Supreme Court ruled in a unanimous decision that the USPS was not a government-owned corporation, and therefore could not be sued under the Sherman Antitrust Act.

input: Chroma key

Chroma key compositing, or chroma keying, is a visual effects/post-production technique for compositing (layering) two images or video streams together based on color hues (chroma range). The technique has been used heavily in many fields to remove a background from the subject of a photo or video -- particularly the newscasting, motion picture and videogame industries. A color range in the foreground footage is made transparent, allowing separately filmed background footage or a static image to be inserted into the scene. The chroma keying technique is commonly used in video production and post-production. This technique is also referred to as color keying, colour-separation overlay (CSO; primarily by the BBC), or by various terms for specific color-related variants such as green screen, and blue screen -- chroma keying can be done with backgrounds of any color that are uniform and distinct, but green and blue backgrounds are more commonly used because they differ most distinctly in hue from most human skin colors. No part of the subject being filmed or photographed may duplicate the color used as the backing.

input: Pam's Replacement

The episode was written by consulting producer Allison Silverman, her first writing credit for the series after joining the writing staff in the eighth season. It was directed by Matt Sohn, one of the series' cinematographers and camera operators, his third directing credit for the series. The episode features a guest appearance from Lindsey Broad, and her character was described as ''Pam's competent and likable pal,'' Cathy. She appeared in a recurring role in the eighth season. The episode also relates to Pam's pregnancy. Jenna Fischer was actually pregnant and her pregnancy was written into the series with Pam and Jim having their second baby. The man who played Robert's skilled drummer friend is Steve Moore, better known as ''The Mad Drummer'' for the viral video he featured in, ''This drummer is at the wrong gig''.

input: Unsuccessful nominations to the Supreme Court of the United States

Justices are nominated by the president and then confirmed by the U.S. Senate. A nomination to the Court is considered to be official when the Senate receives a signed nomination letter from the president naming the nominee, which is then entered in the Senate's record. There have been 37 unsuccessful nominations to the Supreme Court of the United States. Of these, 11 nominees were rejected in Senate roll-call votes, 11 were withdrawn by the president, and 15 lapsed at the end of a session of Congress. Six of these unsuccessful nominees were subsequently nominated and confirmed to other seats on the Court. Additionally, although confirmed, seven nominees either declined office or (in one instance) died before assuming office.
