ALF plays guitar and sings "Cielito Lindo" under Lynn's window.
A traditional Mexican song that ALF parodies and sings with a guitar below Lynn's window when he is trying to apologize for revealing her secret that she was seeing Eddie behind her parents' backs.
ALF's parody lyrics are as follows:
"I'm under your window with my guitar
singing you this small ditty.
Please don't be mad at me anymore.
Did I mention I think you're pretty?
Ay ay ay ay, I'm really sorry.
Somebody just threw a blanket on me.
That's why I'm suffocating."
