"an illusion that really hurts"
There was a faith healer from Deal
who said, "Although pain isn't real,
when I sit on a pin
and it punctures my skin,
I dislike what I fancy I feel
Hey, your rhyming in my time,
But your rhyme well it aint worth a dime;
Cos illusion is real,
So when it hits you you feel,
The need for Aikido is prime.
