One is from the Wizard of Oz.
"Pay no attention to the man behind the curtain."
I don't know, I just like that line.

I like a line from one of the Home Alone movies. It's from one of the first two and it's when Kevin's aunt and uncle are on the plane. Apparently there was a piece of silverware that was valuable, so the uncle repeats over and over:
"Put it in your purse. Put IT IN your purse!!"
I always say that when I'm going to put something im my purse or ask my mom to put something in hers.
