just need to spend more time around people who appreciate that type of humor 
. I do. Nothing is off limits for my friends and I. cannibalism, AIDS, cancer, dead babies, racism, religion, homosexuality, anything related to genital regions… equal opportunity inappropriateness. fun times no guilt
Recently, I babbled on and on about skin cancer and pale skinned people and how black people need to worry less (although should not ignore it completely). An African american acquaintance’s father had had skin cancer…. (I did apologize later) *foot in mouth* rinse and repeat. I’ve started conversations with people I have not met before about cannibalism. Those who cannot handle it make for boring friends 
Over the years, I am learning restraint in work situations.
