Hey, before we begin we want to tell you to try out the NPR1 app for your phone.

Every Thursday this month you can hear episodes of pop culture happy hour a day early.

That's exclusively on NPR1.

A day before they've even been recorded.

By listening, you may alter the future.

Find pop culture happy hour stories

from your local station and more on the NPR 1 app.

It's on your App Store.

We want to encourage you not to go back in time and listen.

You could then alter the reality in which we now live

with grave consequences for you and your children and your grandchildren.

You could alter the course of humanity in a way that could cause all of us great peril.

So please listen to pop culture happy hour

in the present or in the future,

but do not attempt to change the past, no matter how tempting it may be, to change your present reality.

Again, it may seem as if by going back and tinkering with choices and mistakes you've made

in the past, you can improve the present present but all of time is a mobile hanging above a

crib and by by disturbing one all things move. You could you could conceivably just by sending a

thank you note you forgot to send you could destroy all of the fabric of space. So we want to just once again do not

use the NPR1 app to travel into the past.

Use it to listen to programs that NPR has created for your enjoyment.

That is the only recommended use of the app.
