ET- Swiss Cheese

He leaned over the handlebars, feet spinning the pedals. Deep thoughts of space were appearing in his brain, and he felt he could almost glide into the sky. He smiled again; the kids all laughed at him because he only ate Swiss cheese. But so what? What did that matter now, now that he was floating in this incredible power?

He entered the kitchen and opened the refrigerator.

  What could an extraterrestrial eat today?

  He had a strange urge to eat Swiss cheese.

  Moo, said the cheese.

  “Moo,” said the ancient guest, and made himself a sandwich, with mustard.
