In all seriousness, I feel for anyone in the 95% of the country that cannot get fresh sardines. And yes, it is safe to eat the bones in sardines, but it leaves an uncomfortable feeling in one's throat. May I suggest "peeling" the bones out? Its quite simple with sardines.
You are making me hungry for some grilled sardines at the local tapas bar, but I am already in my robe and I have work tomorrow.
Just go in your robe. They’ll think you’re a king or something.
