Unless you have an allergy to corn, raw corn is safe to eat; it might pass through you with vigor (especially if you don't chew it thoroughly before swallowing it), but it won't hurt you.
The USDA, generally on the very safe but a bit paranoid end of the spectrum, says:
After eggs are refrigerated, they need to stay that way. A cold egg left out at room temperature can sweat, facilitating the movement of bacteria into the egg and increasing the growth of bacteria. Refrigerated eggs should not be left out more than 2 hours.
(They also say some very sad things about Easter egg hunts.)
So if you're being strict, three days would be way too long. In reality, you'd probably be okay. The chances of getting salmonella are definitely higher, but are presumably still small (though I can't say exactly how small, of course). Personally, given the price of a dozen eggs, I'd probably play it safe.
Another answer mentions that in the UK eggs are stored at room temperature. That's true in quite a lot of places, but I'm guessing that they've avoided the large temperature swing issue mentioned by the FDA, so if your friend's eggs were refrigerated in the store, the situation's not quite the same as in the UK.

Bearing in mind the salmonella statistics given above., yes it is safe to eat raw eggs so long as you are not very young, very old, or immunocompromised in some way--e.g. HIV, chemotherapy, leukemia, etc.
