The New Bedtime Prayer

Now I lay me down to sleep
I pray my penis I will keep
And if I wake and find it gone
I hope to find it on the lawn

I hope the dog that's running free
Doesn't see that part of me
Many precautions I must take
To keep this thing I love to shake

Much attention I must pay
To make sure I put the knives away
The mower, chainsaw and hatchet too
There's just no telling what she'd do

If I want to keep my manly charm
I must keep it safe away from harm
So I'll cross my fingers and close my eyes
And cross my legs to avoid any surprise
