Light averse

Heavenly bodies up above,
please attend and hark:
I like your sense of duty,
but I also like the dark.

So thank you, Sun, for rising
— your timing’s really ace —
but if you don’t go back to bed
I’ll slap your stupid face.

And thank you, Moon, for rising
— your timing is top-notch —
but if you don’t put out the light,
I’ll kick you in the crotch.
