"Explain it to me like I'm a 2 year-old.".......catch phrase from some movie?

[z106]

SOme other poster on another forum had a question and said "explain it to me like i'm a 2 yr old".

That was a bit of a catch phrase from some movie before ya? OLr was it a tv series?

It's wrecking my head.

Does anyone know what it's from?
