all depends on what you consider gross, eating half cooked bird embryos with cow lactated fat, ground seeds mixed with rendered tallow and fruit oil and covered with boiled tree sap may sound odd, but that is what sunny side eggs, with butter, pancakes and maple syrup is.
worst thing i have ever eaten emotions wise, were prairie oyster and giant pacific Northwest clams.
prairie oyster for usually reason, and the clams, well, they outgrow the shells and live in the sand, and the appearance is ahh more than than slightly reminiscent of the human male's most intimate anatomy. You find them by tapping the ground and watching for the neck or siphon to "piss" a little streamer in the air when walking on the beach at low tide. When you find them, you reach into the sand and grab the siphon and pull, while digging around it with the other hand. As it was described to me, when I asked what I was feeling around in the sand for, 'ever have morning wood? well this is someone elses morning wood" and that is the truth.

if you eat them first and get to like them, then eating them is not bad, if you grab one first then find out what the taste like, you may not want to do that again
