Norwegian Exchange Student 

Defined as a type of foreign exchange students that are extremely attractive, male or female; and their trademark is blonde hair with blue eyes. They come with rocking bodies, and it is said that pure viking blood run through their veins. They appear around high schools spread across the US, and they can be seen surrounded by curious Americans that act as if Norway (frequently called Norwegia) is a magical fantasy kingdom, due to their lack of skills in geopgraphy. The Norwegian exchange students are also frequently asked if they speak norwegish/norwayan/norwayish/or german, and they are often surrounded by less intelligent Americans who believe that the Norwegian exchange students ride their polar bears and/or reindeers to school and live off of hunting wild animals and sleeping in wooden huts.

McKevitt Spousal Exchange Program 

McKevitt Trucking's dating service. Usually consisting ex-wives (or sometimes, husbands) of such truck drivers. There is a head "John" working at the company.

Since the company trucks are governed at granny speed, and the driver's don't have time to date anyone, it's no wonder there's such a service to these drivers that don't have time for lot lizards.

Brian: I didn't know about the McKevitt Spousal Exchange Program...
Dave: Cool! Rosco's wife involved?
Brian: Yup! Up for a threesome!
ROSCO: Can have her... I'm getting a new seat cover through the program...

equivalent exchange 

Humankind cannot gain anything without first giving something in return. To obtain, something of equal value must be lost. That is Alchemy's First Law of Equivalent Exchange.

"Alchemy: the science of understanding the structure of matter, breaking it down, then reconstructing it as something else. It can even make gold from lead. But alchemy is a science so it must follow the natural laws: to create, something of equal value must be lost. This is the principal of equivalent exchange. But I learned that night that some things cannot be measured on a simple scale. My brother and I knew the laws of science, of equivalent exchange. The game required sacrifice, that something had to be taken from us, but we thought there was nothing more we could loose....We were wrong."

~Edward Elric (Fullmetal Alchemist)
