lol I did exactly that before. I trolled a jew a few years ago at the pub with my friends, We were talking about what were the most important historical events in the history of mankind, and a kike, who was sitting next to us, interrupted our talk to kvetch about muh nazi and then mentioned the hollowcost. I made him repeat it several times and ended with "oh you mean the labor camps with swimming pools, soccer fields, maternity yards, music and painting classes...". He got mad and walked away.
