This can't be real, can it? Since last week, a sporadically updated Tina Fey account on Twitter has seen more action, with more-frequent messages emanating from the supposed 30 Rock star and Saturday Night Live veteran. But whoever's updating it is far from clever enough to imitate Tina Fey. Unless this is actually Fey doing a bad impression of herself, thereby demonstrating how moronic most Twitter's users seem in the 140-character format the microblogging service limits them to. That's an idea actually funny enough to come from the mind of Tina Fey.
