Tokio? Hahahah. It was a pun, a pretty punny pun! Hahaha, see, that was another pun, because I said punny, not funny. Get it? I love puns, simply because they're so lame sometimes.
My chemistry teacher used to play this game with us, he would given us a sentence and the name of an element was a pun, so he made us guess which one. For example, "A funny criminal" and we would have to guess silicon (silly-con).
