102. When you have cooked a TARDIS cake
103. When you've made a song about said TARDIS cake
104. When you've come up with your own Time Lord names for you and your friends (Both long Romana style ones, and "The -insert name here-" ones)
105. When you're answer to both questions in

106. When the number 4 freaks you out (also works for Artemis Fowl fans)
107. When your friends tell you they have a doctor's appointment, your only response is looking offended and saying "He has appointments now? I should have been notified!"
