Eggs

At work the other day two customers came up to me and asked me a question (I will briefly point out that male customers often flirt with me or make pointless small talk. I don't mean to sound conceded, but I am a pretty girl, and creeps who come to shopping tend to notice). After the two guys had made the usual pointless small talk and left the isle I was working on, they came back.

"Excuse me, ma'am, but I was just wondering what's the difference between brown and white eggs?"
His friend said, "Yeah I've always wondered..." In my head I sighed and rolled my eyes, because based on the giggling he and his friend were doing, they were just asking to mess with me. I decided that if they were going to take away from my precious work time to mess with me, I would mess with them back.

"One comes from a brown chicken," I said. Because of the person I am, I cannot tell a joke without laughing, so I snorted out my answer, because of my great effort to not laugh. They walked away laughing too. I guess the annoying people at work are the ones that make it the most interesting, eh?
