Had a guy at work that knew I was a Christian and he HATES Christians, so for months, he would sit in the lunch room and make really horrible jokes about my food (I eat healthy and high quality) and how it looks like the sexual organs of a _______ or the bowel movements of a _________, you get the idea. He would also show really bizarre inappropriate content on his phone to co-workers and make really derisive comments about Christians & how bad and hypocritical we all are.
After a couple of months of this, constantly escalating & I could tell he was trying to get a rise out of me, so he could turn around and say "see, Christians don't really turn the other cheek, even this one is a hypocrite" . . . I simply said "Oh come on! Surely you have some other kind of joke" and he started the "oh, did I offend you" bit that I was expecting & so I replied "No, but you have been telling some variation of the same jokes night after night, day after day for months & it is just SOOO old. Do ya have anything else? Is there ANY other way to get chuckles at the table, or is that all the humor you have?"
Since then, he has stayed away from jokes about my food, hasn't shown inappropriate content but once or twice & we are getting along much better. We got on good at the work stations, it was just on breaks that . . . but that is resolved now.
