Hey, we have just met but here's the number! So, Auschwitz or Dachau, maybe? Whichever one you chose.
Why are you making references to the holocaust like that??
It's a joke, it's about these girls who likes dating Jews and taking them to these concentration camps
Joking about the long suffering of a race is not very appropriate, nor is it productive. You should find more creative ways to make people laugh that don't involve antiquated jokes.
