I get special checks almost every time I travel. Only airport that never ever happened anything out of the usual is Narita Airport.
At Miami Int. Airport, so called "random checks" I get selected more than 85% of the times. My parents and sisters are so used to the special treatment that I get at airports, that they just wave at me and yell: "We wait you at the gate/exit".
At JFK too! I not even out of the tunnel, couple of meters out of the plane and police officers stop me and ask for several questions.
At Chicago O'hare: I have to get my shoes x-ray, open all my bags and show all the right documents.
At Los Angeles Int. (LAX): same shit! I even have to take all my baggage to "agriculture inspection" to see if I wasn't smuggling animals, plants or seeds. No matter is it just an connecting flight!
At Frankfurt or Munich Airport, they even get more suspicious. Perhaps speaking in German is not a good idea after all! Asking even how come I can speak German.
At "El Dorado Airport" (Bogota, Colombia) I got to sign an approval to get my torso x-ray (Looking for drugs). As I enter y leave 3 times Colombia in a very short period of time.
I just hate airports!
