What is the proper way to tell a Mormon missionary that you are not interested? —Alyssa's mommy

There seems to be a lot of missionaries in my town and they frequently try to push their religion on me when I am out walking with my daughter. What is the proper way to tell them no? I don't want to be rude, but saying "I'm Catholic" doesn't seem to work, they still try to give me flyers and stuff.

Tell 'em, "Thanks, I'll just google it."

Make them tell you the internet is full of Satan's lies. Then you can say, "That's what the Scientologists say too." They love that.
