I haven't heard it done for a while, but a QF skipper used to always get his F/O and S/O or S/O's to join him in 3 or 4 way banter during introductory P/A's.
It would go something like,
Capt: Hello ladies and gentlemen, this is your captain and my name is X
F/O: Hi all, this your F/O and I'm Y
S/O: And I am your S/O Z.
Capt: So Y, what is the weather for our flight expected to be today?
F/O: Fine weather for today, X.
Capt: Great so the flight should be smooth. Z, what is our expected flight time?
S/O: 12 hours and 10 minutes, X.
etc etc.
It was very entertaining and the passengers seemed to really enjoy it.
