Justice Samuel Alito joked about Black Santa, children in Klan robes and dating websites as the Supreme Court heard arguments Monday in a case weighing a web designer’s bid to avoid working on same-sex weddings because she is a conservative evangelical Christian.

Alito asked whether a Black Santa at the mall is obligated to take a picture with a child dressed up in a Ku Klux Klan outfit even if he doesn’t want to. He also joked about fellow Justice Elena Kagan’s knowledge of dating websites.
