I was hoping to be able to post one more chapter before Christmas, and so I was glad that the internet and my glitchy computer cooperated! Rule 101 is from artsoccer, and thanks to everyone who has sent me ideas! I will be getting to more of them soon, when I start working on rules for the eleventh Doctor.

101- Jenny is real. Donna didn't like the fact that the Doctor kept referring to Jenny as an anomaly. Neither did Jenny.

102- Don't call the Hath fish. Donna had made the mistake of calling a Hath a "Martian fish" in front of Martha. Martha knew them a lot better than Donna did, and since a Hath had saved her life, she didn't appreciate even an unintentional insult to them.

103- Don't complain about the running; sometimes it's the only thing keeping us from being killed. The Doctor had overheard Donna's conversation with Jenny about the amount of running that being a companion involved.

104-Stop asking the TARDIS to move the rooms without warning. Donna had had a bit of a falling-out with the Doctor, and he'd gotten back at her by having the TARDIS shuffle all of the rooms. Donna was lost for two days.

105- Oi! I didn't mean move the rooms back again! Donna had just gotten used to the new arrangement. Now she was lost again.

106- I'm sorry about the room trick; please stop hiding the tea. Donna was finally getting her revenge.

107- Do not ever again let the Doctor drink coffee! Donna hadn't realized what that much caffeine could do to an already extremely energetic Timelord. She was going to return the tea as fast as possible-when she remembered where she'd hidden it.

108-I am no good at Charades, so never again try to make me guess what you need! Donna had gotten very frustrated at the Doctor's attempts to make her figure out what he needed to reverse the cyanide poisoning.

109-I really didn't mean that I should kiss you more often! While they'd been too busy at the time to have a proper discussion about that incident, Donna had brought up the matter later. She'd told him that if that ever happened again, the only "shock" he was going to get would be a slap.

110- Stop humming "The Flight of the Bumblebee" around me. Donna was still traumatized by her encounter with the giant wasp. She promptly pointed him back to Rule # 51 and asked him how he'd managed to learn nothing since then.

111-Don't throw things. On a snow planet, Donna had accidentally woken up a three-headed yeti with a poorly placed snowball. She wasn't sure if that was what had prompted the rule or if it was the fact that the snowball had really been meant for the Doctor.

112-Watch where we're going! When escaping the yeti, Donna and the Doctor had failed to watch the ground. And that was how they ended up stranded on a chunk of ice the size of the TARDIS door, in the middle of a lake.

113-Even if you are mad, stamping your foot while floating on an iceberg is not wise. Donna wasn't arguing that rule; floating on the lake was not fun, but it certainly beat falling in. She wasn't sure she'd ever feel warm again. It was not fair, she insisted, that Gallifreyans were more resistant to cold temperatures than humans.

114-The Sonic Screwdriver is not for putting up cabinets. On one of Donna's visits home, she'd tried to get the Doctor to help Wilf put up some new cupboards in the kitchen.

115-No more visits to libraries! Donna had thought a library was a perfectly safe place to go. She did not like being trapped in a computer and having her face stuck on a greeter.

116-No reading my diary! Spoilers! River Song didn't believe that the Doctor had just dropped it and was picking it up to give it back.

117-I know you're still scared of the Vashta Nerada, but look where you're walking! Donna had walked straight into a pillar because she was nervously glancing at her shadow to make sure it hadn't doubled.

118-Baby animals generally have a mother nearby. The Doctor had been having fun with the baby anteaters-until their mother arrived. Alien anteaters turned out to have three-foot long tongues that were just as good for tangling up supposed enemies as licking up ants.

119-Saying "What could possibly go wrong?" before starting off on a trip is a very bad idea. Donna felt like saying "I told you so," when she found out what had happened on Midnight.

120-Stop repeating everything I say, it is not funny. Donna insisted that it was just revenge for the times he'd been insensitive when she was traumatized. She finally stopped when she saw just how upset the Doctor really was about losing his voice.

Thanks for all the reviews I've gotten. I love them! Have a very Merry Christmas and watch out for Sycorax, or flying fish in fog, or the Titanic, or giant spiders, or…well, you get the idea.
