So we were learning about the different rooms in a typical house and the functions of each. The discussion came to the "bathroom", with a picture showing a bathtub filled with water, a sink, some toothbrushes, etc. As we were talking about the things people can do in bathrooms (e.g. take a shower, brush teeth, wash hands), two kids had to go to the toilet. So I asked the children what people do in toilets. They answered correctly, of course; then, the following discussion ensued:
Kid#1 (aged 3): Go swimming.
Me: You want to go swimming?
Kid#1 nods.
Me: In the toilet?
Kid#1 nods.
Me: Are you sure?
Kid#2 (also aged 3; interrupting): (Kid#1's name) go in the toilet; FLUSH! No more (Kid#1's name)!
Half* the class burst into spontaneous laughter, leaving Kid#1 wondering what the joke was about, and Kid#2 feeling rather smug about himself.
*The other half couldn't understand the joke.

After silently giving Kid#2 credit for being able to give voice to his creative (and even mischievous) thoughts in English, I went after Kid#1 just to make sure he was aware that we were no longer talking about the filled bathtub (where he could have gone "swimming" in) but that the discussion had actually moved on to the "toilet". Thankfully, he eventually realised that he hadn't been following the discussion as closely as he should have before speaking up.
