Finding anything in your eggs, other than an egg, is unusual. I will definitely give you that. That's why Easter is really screwed up if you read too deeply into it.
But I really don't think the gecko instance can be put on the apocolyptic scale......Interesting yes, horsemen material? No.
I used to live around geckos. And lots of strange critters....They get into everything because sometimes they know better, and sometimes no.
Alright fine, it's a gecko of the apocolypse, everyone head to your basement and pray now.
