"Little Johnny in Sunday School" joke

A Sunday School teacher of pre-schoolers was concerned
that his students might be a little confused about Jesus
Christ because of the Christmas season emphasis on His
birth. He wanted to make sure they understood that the
birth of Jesus occurred a long time ago, that He grew up,
etc.

So he asked his class, "Where is Jesus today?" Steven
raised his hand and said, "He's in heaven." Mary was called
on and answered, "He's in my heart." Little Johnny, waving
his hand furiously, blurted out, "I know! I know! He's in
our bathroom!!!"
The whole class got very quiet, looked at the
teacher, and waited for a response. The teacher was
completely at a loss for a few very long seconds. He
finally gathered his wits and asked Little Johnny how he
knew this. And Little Johnny said, "Well... every morning, my
father gets up, bangs on the bathroom door, and yells
' Jesus Christ, are you still in there?'!"
