A Good Advice

Once Professor Cheng Man Ching
said: "Forget 'bout everything
which the western doctors told
how to fight a lousy cold.

Just sit down beside your bed,
on the bed-post place your hat,
drink some Scotch, that’s my advice,
til your hat appears there twice.

Go to sleep then in your bed,
have sweet dreams and a good sweat.
If the cold beats the advice,
just repeat this treatment thrice!"
