Context paragraphs:
Puppy Bowl: The Puppy Bowl is an annual television program on Animal Planet that mimics an American football bowl game similar to the Super Bowl, using puppies.  Shown each year on Super Bowl Sunday, the show consists of footage of a batch of puppies at play inside a model stadium, with commentary on their actions.  The first "Puppy Bowl" was shown on February 6, 2005, opposite Super Bowl XXXIX.  The puppies featured in the "Puppy Bowl" are from shelters.

1978 Miami Dolphins season: The 1978 Miami Dolphins season saw the team return to the NFL playoffs for the first time since 1974, with an 11–5 record.  Quarterback Bob Griese missed the first seven games due to a knee injury.  The Dolphins got off to a 5-2 start behind back-up Don Strock.  Upon Griese's return the Dolphins earned a birth to the playoffs as a Wild Card.  Helping to lead the Dolphins back to the postseason was Running Back Delvin Williams who set a team record with 1,258 yards rushing on the season.  In the first playoff game involving two Wild Cards the Dolphins were stunned 17-9 by the Houston Oilers at the Orange Bowl.  In the process the Dolphins set two notable records: scoring first in all but one of their sixteen regular season games, and never trailing at any point in eleven games.  The former record was equalled by the 2004 Patriots, and the latter was beaten by the 2005 Colts.

Super Bowl XXXIX: Super Bowl XXXIX was an American football game played between the American Football Conference (AFC) champion New England Patriots and the National Football Conference (NFC) champion Philadelphia Eagles to decide the National Football League (NFL) champion for the 2004 season.

The game was played on February 6, 2005, at Alltel Stadium (now known as EverBank Field) in Jacksonville, Florida, the first time the Super Bowl was played in that city.

Dallas Cowboys: The Dallas Cowboys are a professional American football team based in the Dallas–Fort Worth metroplex.

The stadium took its current name prior to the 2013 season.  The Cowboys joined the NFL as an expansion team in .  The team's national following might best be represented by its NFL record of consecutive sell-outs.  The Cowboys' streak of 190 consecutive sold-out regular and post-season games (home and away) began in 2002.  The franchise has made it to the Super Bowl eight times, tied with the Pittsburgh Steelers, and the Denver Broncos for second most Super Bowl appearances in history, just behind the New England Patriots record nine Super Bowl appearances.  This has also corresponded to eight NFC championships, most in the NFC.  The Cowboys have won five of those Super Bowl appearances, tying them with their NFC rivals, the San Francisco 49ers, and the AFC's Patriots; all three are second to Pittsburgh's record six Super Bowl championships.  The Cowboys are the only NFL team to record 20 straight winning seasons (1966–85), in which they only missed the playoffs twice (1974 and 1984), an NFL record that remains unchallenged.
