King of the Hill (1997)

Season 3: Episode 23

While studying for her beauty school exam, Luanne sees someone bouncing on Buckley's old trampoline. It's Buckley, who has come back as an angel. Hank and Peggy think Luanne was hallucinating after using too many hair-dying chemicals, but Hank's friends come to believe in the existence of Buckley's Angel. But Luanne finds that Buckley isn't much more help to her as an angel than he was when he was alive.
