Rare Professor Relationship

One of my professor has a twisted sense of humor. We cuss at each other periodically and always give each other backhanded compliments, never straight forward ones. Has anyone had a similar with a relationship with a professor? Did you ask them for a letter? I'm just asking out of curiosity. I absolutely love my professor so they are going to be one of my letter writers.
