Never take a parrot to church!

Never take a parrot to church!

A pastor asked one of his members not to bring their parrot back to church, because the parrot was cussing and being rude to everyone.
The very next week, the man was back in church and his parrot was perfectly behaved.
The pastor asked him how he was able to make the parrot behave so quickly?
The man said: I taught him to say Amen when I pull his left leg, and hallelujah when I pull his right leg.
The pastor asked: What if you pull both legs?
The parrot said: I fall on my aXX stupid!
