First: not all employees. Second, i think it really depends on how your employees need job security. I don't (most IT people in my country do not), so probably not playing games like that. I'll still be polite, and i'm really a good target for jokes, its rare i don't find one funny, but if you fire me, i'll just go my way and find another job. I interview well, and i do not need money. [edit] I also have to add that some people on the spectrum (who were called "Asperger" a few years ago in my country) have troubles pretending and lying, so target those if you're afraid you're being lied too. They aren't easy to work with if you don't understand them (you really have to make them trust you and their environment, else they won't communicate as much as they should to be able to work in a team), but it can really be worth it.
