That's a fun poem for making your Chinese-speaking friends laugh. For English speakers, a similar kind of tongue-twister is The Chaos (Dearest Creature in Creation):

I'm (still) trying to learn Chinese, using my own web app to split words, romanise them, and translate them separately.
The hardest challenge for Chinese NLP is word spacing. I'm amazed that they still haven't welcomed the space character. English without spaces could be really confusing! Consider what happened with URLs: "thepenismightierthanthesword", "expertsexchange", "psychotherapist". That's amusing for single words, but I wonder if we could go longer.
If there's any poets here, I'd like to hear your best examples of English sentences that make sense, but with a different meaning, if spaces were added in different places.
