canadian border patrol 

When doing it doggystyle, take your partner over to the window so he/she is facing out. Take a break for a few moments, and covertly invite a friend to take your place. While he continues, she assumes it is still you behind her, so then walk outside the same window and wave to her as if you were simply passing by.

Me and Kevin pulled a canadian border patrol on her, she didn't know what happened and she went nuts.
I'm gonna visit her in the asylum in a few days.

Canadian Border Patrol 

This hilariously tragic sex prank is achieved through the following: You begin normally having sex, you then tell her to get on all fours (Doggystyle), all the while covertly aiming her towards a window, immediately after, your friend will come and switch places with you. Then, you will calmly walk past the window, then turn and wave at your misguided partner.

Dude: OMG MAN, MEMBER THAT BITCH JULY?
Guy: Yeah...?
Dude: Me and Man totally pulled a Canadian Border Patrol on her.
Guy: Dude... you're fucked up... In a funny kinda way!
*High five*

US-Canadian Border 

Border between the North American nations of Canada and the USA. Easily traversed if you are a Canadian or American citizen, less so if you are from any other country (including EU or Commonwealth nations).
Be prepared to pay $6 dollars to enter the United States from Canada (entering Canada is free). The fee CANNOT be paid by credit or debit card or with Canadian dollars, nor is there anywhere nearby from which American money can be withdrawn in most cases. Also, be prepared to fill out a ridiculous immigration card which asks you questions including "Were you in any way involved in the Nazi regime in Germany between the years 1939-1945" despite the fact your passport clearly states that you were born in the late 1980's.
Generally, expect to be treated with far more suspicion by the American border guards than the Canadians. If you are planning to stay in the USA longer than a few days, you may be required to provide proof that you have the money to fund your trip so they are satisfied you won't try to work in their country, since they seem convinced anywhere outside North American is some kind of God forsaken war torn hell hole.

When I was crossing the US-Canadian Border I had to pay $6 for the privilege of filling that stupid green piece of card they give you, then convince them that I didn't need to work in their country to send money home to feed my family since I'm from Britain, not Yemen.
