Ha ha.

I'm grateful to my Civil Service retirement magazine for this one -

A primary school teacher was observing her class of children drawing. She would wander around from time to time to see how they were getting on. As she got to one little girl who was working away diligently, she asked what it was she was drawing. "I'm drawing God" replied the girl. "But" said the teacher, "no-one knows what God looks like". Without missing a beat or looking up from her drawing, the girl replied "They will in a minute"!
