Dear Mr. or Mrs. Spider,

Keep to your side of the shower
take out the:
mosquitos
gnats
flies
other spiders who won't sign this agreement

keep to your side of the shower
we'll get along just fine

if it has more legs than I do
have at them, hide the bodies when you're done
I don't want to know what you get up to

keep to your side of the shower
we'll get along just fine

I promise to leave your web alone where
I see those eight shiny black eyes watching (why do you have one for each eye?!)

keep to your side of the shower
we'll get along just fine
