Continuity mistake: When Meg, as X-Men's Quicksilver, starts to spite her whole family at the speed of light at the beginning of the episode - just after Chris sneezed in front of everybody - she initially throws his hat away from him, but in the next shot when she gets back on her seat, Chris' hat returns resting to his head.
Answer: Lacey Chabert was the actress who originally voiced Meg in early episodes. She left of her own accord due to being in school and other acting work; Seth MacFarlane has stated there was no tension with her leaving, but it makes for a handy joke for the show.
