Why apples are oranges?

[Doktor Howl]

It's not a proper apple eating contest unless you're eating the seeds.

I assume you mean the whole core too. Everything but the stem? We may have a new format of competition here! 

This is the point where I remind you that apple seeds contain small amounts of cyanide, and eating lots of them will absolutely kill you.

I didn't know that.

It is the fabled second half of the joke.

That's our story, anyway,.
