What Are the Chances?

I got an email this morning with a few free images for Mother's Day - meant to be used as screensavers, Facebook cover photos, etc.  I was not that excited until I noticed just how perfect these two (in particular) were for me.  My little giraffe and elephant babies.

What are the chances that they would choose those two animals and have them be an appropriate match (giraffe/daughter, elephant/son)?  Must be a good sign for today!
