I'm actually making a serious point, i'm not even trying to be racist. Let's say he takes one of the jokes the wrong way (we all have to admit it happens, humor is a funny thing) and it becomes a real issue. He see's an opportunity, gets a lawyer, and it becomes a cluster fuck of a law suit.
Is it likely? No, but it CAN happen. It is generally the harmless actions and the people you NEVER expect that end up fucking you.
