Devilled, scrambled, hard-boiled and decorated with bunny stickers, sure. But not sliced. I'd love to fuel my paranoid fantasies and imagine that all my friends just think I'm not good enough for sliced eggs, but I never use mine either. So I think it's just that we don't eat many salads. Now, the important thing when making breast testicles is that they be perfectly round.
Nobody likes a lopsided testicle in their fruit salad.
