There was a Scuba Diver...

When the last breath for me is past,
fulfil a request of which to be my last,
The ashes of mine be placed within,
within a scuba cylinder, together with a mask and fin,
Atop the cylinder a stainless steel plate should sit,
with these words to be clearly written on it:

"There was a scuba diver, he'd dive 'most round the clock,
He used to introduce himself as 'Daniel, Daniel Kwok',
Resting here now he lay, within this tank and upon this rock."

When the time comes do grant him this simple final wish,
following which he will finally rest with all the fish...
