Dude--just take a couple hundred more steps, and there'll be another egg. The game will keep obliging you so long as you're that bored. "Ah, it's you! We were raising your Pokemon, and my goodness we were surprised! Your Pokemon was holding an egg. We don't know how it got there, but your Pokemon had it. You do want it, don't you?" Such a clever old man. He knows exactly how it got there, and he's produced THOUSANDS.
