So Bill Murray, Luke Wilson, or some other laid-back, always-drunk-even-when-sober character is at a party. He approaches a girl he’s never met while his uptight friend tries to tell the other girl that this guy is trouble. As he’s telling her something really important, Bill (or Luke, or someone else) goes through this schtick with the girl:
GUY: Hi, I’m {name}.
GIRL: Oh, hi, I’m–
GUY: Don’t tell me! It’s… Aaaaaaa…Grrrrr…Emmmm…Jiiii…Llllooooouuuuurrrr…Kelly!
GIRL: Oh my God, that’s amazing!
So, what movie is this, and who is playing the smooth talking guy?
