Duck and Cover

It comes from this thread.

Shamus also brings up the point that most of us don't even bother to listen to all of the dialogue...we just click right through it. This is true. I personally only play with subtitles... then I read the subtitles faster than the voice actor and if I am at the end of the line, I skip to the next one.

But I'll guess thats how it was planned. Getting the image into the heads of the people, so they will remember it later. Same as with the power armor in Fallout 3. You saw the brotherhood dude the first time and then again and again and in the end he was on the cover.

This one above looks very generic to me.
