@cierrahailey So you could come up with a "hole in one" or some golf reference(I don't know the game so can't get more detailed). But for the baseball reference you could talk batting averages and rbis, to lead into the "home run". Or you could go with a bottom of the ninth bases are loaded and two strikes, etc...
You could do something also for the lawn mowers:
John Deere has pink and/or green children's power wheels lawn mowers.. you could gget am image of each off line and print them out in a picture size. Wrap the pregnancy tests in a little box with the pics inside and write something like "Which do you think? Pink or green take a look and see what I've seen". The tests being just below so then he has to open it. And a Congratulations memo atached to the tests themsleves.
