I'm sorry, 10000kbps, but I haven't a clue as to who this Guy Messypants fellow is.

I always thought that it was just an old saying, meaning that it's a tough old world out there. Survival of the fittest and all that.

thank you!
Lord Ellpus,thanks for your answer!
Guy de Maupassant is a famous French writer who wrote "Ball of Fat"(Boule de Suif )

I have no idea. The man wrote many short stories. Try to use Google and find out.

OK!I will do that!
