Possibly Some Confusion

I was reading a story to the boys this evening in which a character was left unconscious. This led to the following exchange.

Michael: What’s “knocked out”?
Daniel: I know, I know, I know.
Michael: What?
Daniel: It’s when you fall down like this [collapses on bed] and sort of go to sleep.
Michael: What?
Daniel: Like France did to Ireland in the world cup when it put out its hand and knocked us out.
