Martha's phone rarely rang, in fact it was only used in complete emergencies. So when the phone's annoying ringtone went off, The Doctor didn't hesitate to answer. "Martha?"
"No," a voice that certainly wasn't Martha's answered.
"Who is this?" The Doctor asked. "How did you get this number?"
"I'm you," the voice said after a moment's hesitation. "I'm your Eleventh incarnation, and I have to warn you-"
"No!" The Doctor cut The...Doctor off. "I'm hanging up."
"You can't!" The Eleventh Doctor shouted back. "This is important! Whatever you do...you can't...just promise you won't...don't...don't eat the pear!"
The Tenth Doctor had preparing himself for the worse. "What?" was all he could say.
"Just don't do it! I thought that my taste buds had changes, but no. Trust me, you don't want to experience it. I don't want to experience it."
"Goodbye," The Doctor said, hanging up the phone.
About a year later, Amy and Rory ran into the room at the sound of a loud shout. "What happened?" Amy asked.
"He was right," The Doctor told her. "I hate pears!"
