Alright, here we go, pick a character from any one of the following fandoms and I'll give you my 3 favorite moments with that character (pending my actually remembering that character)
Dr Who (New Who Only)
Life On Mars
Ocean's 11 (All three movies.)
Okay, I think that's enough fandoms. Fair warning, obscure characters will probably get more along the lines of "three moments I can actually remember.
