The western honey bee or European honey bee ("Apis mellifera") is the most common of the 7–12 species of honey bee worldwide.
 The genus name "Apis" is Latin for "bee", and "mellifera" means "honey-bearing", referring to the species' tendency to produce a large quantity of honey for storage over the winter.
Hylaeus longiceps is a species of bee, also known by the common names longhead yellow-faced bee or Hawaiian yellow-faced bee.
 It is endemic to Hawaii and known from only six populations.
 In September 2016, along with six other Hawaiian bee species, "H. longiceps" was listed for protection under the United States Endangered Species Act.
 This marked a first listing for any bees species in the US.
Peponapis pruinosa is a species of solitary bee in the tribe Eucerini, the long-horned bees.
 Its common name is eastern cucurbit bee.
 It may be called the squash bee, but this name can also apply to other species in its genus, as well as the other squash bee genus, "Xenoglossa".
 This bee occurs in North America from the East Coast of the United States to the West Coast and into Mexico.
 It is an oligolege, specializing on a few host plants, the squashes and gourds of genus "Cucurbita".
 Its range expanded as human agriculture spread throughout North America and squash plants became more abundant and widespread.
 It may also have spread naturally as the range of its favored wild host plant "Cucurbita foetidissima" expanded.
A bee bole is a cavity or alcove in a wall (the Scots word "bole" means a recess in a wall).
 A skep is placed in the bee bole.
 Before the development of modern bee hives (such as the design published by Lorenzo Langstroth in 1853), the use of bee boles was a practical way of keeping bees in some parts of Britain, although most beekeepers kept their skeps in the open covered by items suitable for the purpose, such as old pots or sacking.
 The bee bole helped to keep the wind and rain away from the skep and the bees living inside.
 Bee keeping was a very common activity in the past before sugar became plentiful and affordable as a sweetener.
 Demand was also a high for beeswax for candles, especially from the prereformation churches, cathedrals, and abbeys; tithes and rents were often paid in honey and/or beeswax, or even bee swarms.
The lithotomy position is a medical term referring to a common position for surgical procedures and medical examinations involving the pelvis and lower abdomen, as well as a common position for childbirth in Western nations.
 The lithotomy position involves the positioning of an individual's feet above or at the same level as the hips (often in stirrups), with the perineum positioned at the edge of an examination table.
 References to the position have been found in some of the oldest known medical documents including versions of the Hippocratic oath (see lithotomy); the position is named after the ancient surgical procedure for removing kidney stones and bladder stones via the perineum.
 The position is perhaps most recognizable as the 'often used' position for childbirth: the patient is laid on the back with knees bent, positioned above the hips, and spread apart through the use of stirrups.
Centris pallida is a species of solitary bee native to North America.
 It lacks an accepted common name; however, it has been called the digger bee, the desert bee, and the pallid bee due to its actions, habitat, and color respectively.
 The solitary nature of this bee allows for a dual-strategy mating system which produces an evolutionarily stable state resistant to invading strategies.
 These bees have also evolved to withstand the high temperatures of their native habitat.
 "C. pallida" routinely has internal temperatures within 3 degrees Celsius of death.
In woodworking, a knee is a natural or cut, curved piece of wood.
 Knees, sometimes called ships knees, are a common form of bracing in boat building and occasionally in timber framing.
 A knee rafter in carpentry is a bent rafter used to gain head room in an attic.
The two-spotted bumble bee ("Bombus bimaculatus") is a species of social bumble bee found in the eastern half of the United States and the adjacent south-eastern part of Canada.
 In older literature this bee is often referred to as "Bremus bimaculatus", "Bremus" being a synonym for "Bombus".
 The bee's common name comes from the two yellow spots on its abdomen.
 Unlike many of the other species of bee in the genus "Bombus," "B. bimaculatus" is not on the decline, but instead is very stable.
 They are abundant pollinators that forage at a variety of plants.
A Bees Knees (or Bee's Knees) is a Prohibition Era cocktail made with Gin, fresh lemon juice, and honey.
 It is served shaken and chilled, often with a lemon twist.
Karsk (also called Kask) is a Scandinavian cocktail containing coffee together with moonshine or vodka, and sometimes a spoon of sugar (enthusiasts often consider moonshine exclusively to be appropriate as an added component, as it has no inherent taste like other alcoholic beverages).
 Broader, it can also be found in other parts of Scandinavia.

Question: what does Karsk and Bee's Knees have in common?
Answer: cocktail
