The Catholic Response to Jehovah's Witnesses

A Jehovah's Witness knocks at your door. Do you:

a) Not answer.
b) Invite them in for tea and biscuits.
c) Tell them to renounce their heresy and that there is no salvation outside of the Church.
d) Politely tell them you are Catholic and believe in the teachings of Holy Mother Church, but thank you anyway.
e) Shower the witnesses with Rosaries from your window.
f) Tell them there is not enough time to talk as you have to go to hospital for an urgent blood transfusion.
g) Tell them you are not in.
h) Tell them that you've mathematically deduced that Heaven is probably full now, as there must have been at least 144,000 Jehovah's Witnesses who have already lived and died and now enjoy the Beatific Vision and you fear we are out of time.
i) Tell them that you'd love to chat, but you've hunkered down in the house with 10,000 cans of tinned spaghetti just in case the Apocolypse is around the corner and you literally can't open the door because you've put the wardrobe there.
j) Tell them you have a stack of spare Papal Encyclicals lying around in the flat, could you have their address so you can pop round one day.
k) Tell them it was divinely revealed to you in a dream last night that Barry Manilow is the prophet we have all been waiting for and that yes, he is 'the One'.
l) Invite them in and tell them you'd love to join Jehovah's Witnesses but you've just this second started a cult of your own, and ask if they'd like to join your one, while pouring petrol on your furniture and striking a match.
