it; for example a 1983 journal is quoted as saying, "Whether we hammer, or hoe, whoop or holler, as they say, slap five up high, down low, you're too slow, we do it with the rhythmic motif that leads to harmony." The title song for Lay on Five, a BBC children's television programme broadcast in 1985–86 featuring Floella Benjamin, ended "..too slow to Lay on Five." The too slow variation is in the 1987 film The Principal in a scene where Principal Rick Latimer (James Belushi) does it to Arturo Diego (Jacob Vargas). In the New York Times archives, the earliest reference is from 1993 when Arnold Schwarzenegger did it with the son of a film-crew member while on the set of Last Action Hero, saying: "Let's have five. Five high. Five low," at which point Schwarzenegger pulled his hand away saying "Too slow." The boy reportedly laughed. Schwarzenegger did it originally in the 1991 film Terminator 2: Judgment Day, when John Connor (Edward Furlong) teaches the Terminator (Schwarzenegger) to "Gimme five. Up high, down low, too slow." In 2008, They Might Be Giants released the song "High Five!" on an album for children titled Here Come the 123s, with lyrics "High five! Low five! Slap me five! Down low! Too slow!," a gesture described in the song as "old school" a slang term usually meaning something from a prior generation. The rhyme bears a striking resemblance to a very old rhyme, possibly medieval, used by blacksmiths to teach apprentices how to best operate a bellows in a way that maximized its efficiency by opening it fully and quickly, while closing it slowly. The didactic rhyme is "Up high. Down low. Up quick. Down slow; And that's the way to blow." Air five An air five is a variation where the hands of the participants never actually touch, needing only line of sight to make the gesture. It has an advantage for participants who are otherwise too far apart to achieve physical contact at the moment of the gesture. The participants may simply pretend to high five, or add an imitation sound of hand slapping. Also known as the wi-five, a mix of "wireless" and "high five" with a pun on Wi-Fi, a wireless computer technology. Celebrations National High Five Day is a project to give out high fives and is typically held on the third Thursday in April. According
