While we're on the topic of Jack Bauer, and how he answers the phone, I'd like to point out that he ALWAYS identifies himself on his phone, when he's calling and answering, "This is Bauer!"
I'm so tired of people who don't know how to communicate on the telephone. People call ME and say MY name as a greeting and I say, "that's me, who are you?". Or people who call and just say, "HEY," and I'm supposed to know who they are. I started copying my dad by announcing myself when I pick up the phone, like Jack Bauer. It saves one step in the greeting part of the conversation. I just say my name; the caller doesn't have to wonder if it's the right number or who in the house is answering. Or if you use someone else's phone, and the person who answers thinks it is another callerID, you should really help them out and let them know who is calling, not make it a guessing game.
I was trying to think of other actors/characters who answer the phone like this, by announcing themselves. On StarTrek TNG, Patrick Stewart answers his communicator like that. Can anyone else list some actors/characters that do the same?
