Little Johnny was at school one day and the teacher was teaching Religious Education.  "OK" said the teacher.  "I've told you a bit about how good people go to Heaven and bad people go to Hell, but if you're a good person and make it into Heaven, then which part of you do you think makes it into Heaven first?"

And with that some of the kids put their hands up.  The teacher chooses a kid in the centre of the class and says "OK Lucy, what part of your body goes to Heaven first?"

Your heart, Miss" says Lucy, adding "because you told us Jesus is all about love, and love comes from the heart, so your heart would make it into Heaven first."

"Good answer, Lucy" says the teacher.  "Let's have another answer.  Christopher - what part of your body do you think gets to Heaven first?"

"Your soul gets to Heaven first, Miss" says Christopher "because when we die the body becomes an empty shell and the soul ascends to Heaven."

"Very good answer, Christopher" says the teacher.  "It sounds like you've learned a lot.  Let's have another answer."

And with that the teacher spots that Johnny isn't really concentrating, so she decides to catch him out.  "OK, Johnny" she says.  "And what do you think?"

"What do you mean, what do I think?" retorts Johnny, clearly bored by the entire lesson.

"Well, Johnny, if you had been listening instead of not paying attention you would know what the question was.  What part of your body do you think gets to Heaven first if you're a good person and make it into Heaven?"

"Your feet, Miss" replies Johnny.

The teacher looks at Johnny strangely for a second and then replies, "Your feet?  Why do you think that your feet get to Heaven first?"

And with that little Johnny replied  "Well, Miss, I had to get up to go to the toilet last night but I heard some funny noises coming from Mummy and Daddy's bedroom.  Anyway, I peeped round the door to see what the noise was about and Daddy was on top of Mummy and she had her feet right up in the air and was going "Oh God, Oh God, I'm coming!!!"
