Later on, I got "The Rest of the Story" from my friend. Apparently the eggs were laid during the hot part of summer, and the heat "cooked" the eggs. With the frosty temps we'd gotten during the past few days, the eggs froze, and when I turned the heater on in my car, it caused expansion of the inner egg contents, and then BOOM! I suppose I should be thankful the eggs were cooked - if they weren't, it would have been much harder to clean out my car after the disaster!
Enjoy your day today -
