"He'll Have To Go" by Jim Reeves.

"Go? Whaddya mean Go? I just got here!"

How about these for song titles:

Ain't Never Gone To Bed With Ugly Women, But I've Sure Woke Up With A Few
She's Looking Better After Every Beer
Her Teeth Was Stained But Her Heart Was Pure
You're The Reason Our Kids Are So Ugly
She Got The Ring And I Got The Finger
My Wife Ran Off With My Best Friend And I Sure Do Miss Him
If I Had Shot You When I First Wanted To, I'd Be Out Of Prison By Now
I'm So Miserable Without You, It's Like You're Still Here
I Wouldn't Take Her To A Dog Fight 'Cause I'm Afraid She'd Win
I Liked You Better Before I Got to Know You So Well
How Can I Miss You If You Won't Go Away?
If The Phone Don't Ring, You'll Know It's Me
