Practice Makes Perfect

Now I lay me down to sleep,
I pray the Lord my soul to keep,
If I die before I wake;
Practice makes perfect, no mistakes.
I've done it countless times before.
Because sleep is just a dry run.
In the morning I'll awake after one more,
Just the end of another one.
Getting ready for the final show,
My one last truly big blow!
My ultimate finale
And performance fatal.
No amatuer morbidity,
Just professional delivery;
For sleep is but practice for death.
