One line, executed perfectly, is all that's needed to become iconic. Goodfellas is one of the most well-remembered films of all time, but there's one line, and one character, that I find myself quoting all the time. Jimmy is introduced by Henry Hill: "And then there was Jimmy Two Times, who got that nickname because he said everything twice." He then replies with what I now say whenever I'm announcing that I'm getting something – "I'm gonna go get the papers, get the papers." It's simply iconic, simply iconic.
Best line: I'll repeat it, WHY NOT... "I'm gonna go get the papers, get the papers."
