And a suggestive St. Patrick's Day to you!

I realize that this is late in coming, but I've been wanting to post this since before I had this blog. Around St. Patrick's Day, I had a therapy activity for the kids I worked with this past semester that involved decorating a large shamrock. The kids would take turns, and after each turn could choose a different decorative item - one of which included drawing with markers. After completing a session, I hung the shamrock up on the class display board, and noticed something. This particular shamrock had been decorated with balloons. But they reminded me of something distinctly different....
I've gotten at least two other opinions that go along with mine, so I know it's not just because I'm trying to get pregnant.
Do you see it?
