How do i get along with this new supervisor?

I worked for a supervisor just like this one at another job, now i work with the state and i have run into this same personality. They both have the same characteristics, they like to joke now and work later, they are very inappropriate speaking of es and vibrators and other ual things at work, and for some reason they both dont seem to take a liking to me. Well the last supervisor i had that was this way ended up firing me with no reason given.This one wouldnt have an easy go trying to fire me because this is the state instead of the private sector. Still i can sense that she would rather i not work with her. What do i do? Naturally I am against trying to fit in, i do my job and go home of course i do the usual niceties at times like greeting them but when they look at me right in my face and say nothing, i dont say anything either so yeah i guess you can say i really dont try to hard to be liked cos i really dont care about fitting in but i want a decent work environment any suggestions?
