What I did when I found out I was pregnant was to upload a picture of the test on his laptop and put it as the wallpaper. I'd also bought a card and put the tests I'd take so far in it. When he came in the room I told him that his computer kept making this weird noise all the time so he loaded it up to check and he saw the wallpaper. He didn't even know what it was! He was like, what's this, then he asked me if I knew what it was and showed me the screen. I looked at it and handed him the card.
Here are a few pics from then:
