The Twilight Zone1959

Roger Shackleforth:
I'm in love with somebody named Leila, but she's not in love with me, and... I don't know why I'm telling you this.

Professor A. Daemon:
I do. I can arrange it so she'll love you.

Roger Shackleforth:
How?

Professor A. Daemon:
I promise you she'll never leave your side. When she isn't telling you she loves you, she'll be gazing at you lovingly. She won't even eat before you do, and nothing will be too much for you to ask of her. She'll worship you. She'll beg for kisses, and weep for joy at your touch. And if in passing time you should perhaps look at another girl, or, even do a little more than look, she'll feel hurt. But she'll forgive you, and love you just the same. Frankly, you'd get the same shake from a cocker spaniel.

Roger Shackleforth:
But that's wonderful! That's all in the world I want: my Leila's love!

Professor A. Daemon:
[Talking to himself] His Leila's love. If it isn't his Leila's love, it's his Dorothy's love, his Rea's love, or his Gwen's love.
