– I’m taking mathematics and theology.
– And… who teaches you maths?
– Mr Theodore.
– But I thought Mr Theodore taught theology.
– He taught theology last term. But the maths teacher left, and now Mr. Theodore will be taking us for maths.
– Well who’s taking you for theology now?
– Mrs Theodore.
– I didn’t know Mrs Theodore had studied theology.
– That’s how she met Mr Theodore.
