The Frustration of a Pencil Out of Lead

I don't like mechanical pencils
Because they are usually out of lead
And I find it frustrating, to say the least
But there is something even more frustrating
And that is when my "pencil" seems to run out of lead
Which usually happens at night when I'm in bed
Feeling that i am in the mood for some loving
Yet, the feeling is mostly in my mind
While my "pencil" is . . .
Well, you get the picture
Of a pencil out of lead
Now that is frustrating!
