A dial-in time is a term used in drag racing to claim how fast a racer's car is. Dial-in times function to determine which cars race against each other. If one car's dial-in time is significantly slower than another's, the slower car is given a handicap (which is done in E.T. bracket racing). The purpose of dial-in times is to make the race fair - so if a racer beats his or her dial-in time, he or she is automatically disqualified. Dial-in times can, however, be manipulated to be significantly slower than the car actually performs, in a technique called sandbagging.

A car that runs 14.28, 14.30, and 14.32 seconds in quarter-mile practice runs could have a dial-in time of about 14.30 seconds. If the racer sets the time too low at 14.28, there is no guarantee that the car will actually run that fast in the real race, and time will be lost in the handicap to the opponent. If the racer sets his or her dial-in time too high at 14.32, there is a good chance the car will outperform that time and he or she will be disqualified.

Katheryn Elizabeth Hudson (born October 25, 1984), known by her stage name Katy Perry, is an American singer, songwriter and actress. Perry grew up with gospel music, and during her first year of high school she pursued a music career as Katy Hudson, releasing her first studio album called Katy Hudson which failed to chart. She recorded a solo album later, which was never released. After signing with Capitol Music Group in 2007, her fourth record label in seven years, she adopted the stage name Katy Perry.

She first gained recognition with the release of her first mainstream album, One of the Boys in 2008, which spawned three Billboard Hot 100 top-ten songs—"I Kissed A Girl", "Hot n Cold" and "Waking Up In Vegas". Perry supported the album with her Hello Katy Tour. In 2010, her third studio album, Teenage Dream (2010), which topped the Billboard 200 chart, and spawned five number one singles—"California Gurls", "Teenage Dream", "Firework", "E.T." and "Last Friday Night (T.G.I.F.)"—Teenage Dream was the only album (after Michael Jackson's Bad)—to do so, and the first female in history to achieve this milestone. She embarked on the California Dreams Tour, which grossed nearly $60 million worldwide. Perry re-released the album under the name of Teenage Dream: The Complete Confection on March 26, 2012, and the re-release has already spawned the number-one single "Part of Me".
