Back to normal...or is it?

Jon walked out of the transporter followed by his mom. Jon looked at his mom and frowned. Stood in front of him was himself! "Mom?" said Jon. "Oh my God," said Jon's mom. "You're me and I'm you!" Jon looked down at himself. His bottom half was still him mom's but now a pair of breasts were obstructing his view. He was wearing his mom's top! He was wearing his mom's nail varnish. His mom's hair flopped in front of his eyes. HE WAS HIS MOM!!!
