The Teacher

I'd like to be a teacher, and have a clever brain,

Calling out, "Attention, please!" and "Must I speak in vain?"

I'd be quite strict with boys and girls whose minds I had to train,

And all the books and maps and things I'd carefully explain;

I'd make then learn the dates of kings, and all the capes of Spain;

But I wouldn't be a teacher if. . .

I couldn't use the cane.

Would you?
