Knock On Birdbath Ice?

In Florida, this morning, it was a tad nippy. I heard our songbirds talkin... One laughingly said to the other, after narrowly escaping being smashed against a cold, icy windshield, "It's a good morning to be alive, knock on birdbath ice"🤣! After my last few months, I'm thankful to be alive, but no need to knock on wood. Unless it's the door to God's heart. Signed, Sounds Like A Song
