Stranger with You: One and a Half Episodes

Someone explains to me how this happens, because it's happened to me before.

I have seen the show Two and a Half Men exactly one time in my entire life. It was four months ago, in Guadalajara, at a friend's house. In that particular episode, the hard-living best friend of Charlie Sheen's character (played by Emilio Estevez) had just died; Charlie Sheen's character is worried about his own mortality, and the following joke is made during a funeral in a dream sequence:

  Emilio Estevez: Nice turnout.
  Charlie Sheen:  Yeah, standing room only.
  Emilio Estevez: Goes to show you. Give the people what they want...
  Charlie Sheen:  You mean the open bar, right?

Today, on my seventh day at a new apartment, my roommate turned on the TV in the living room and I heard the following dialogue:

  Voice of Emilio Estevez: Give the people what they want...
  Voice of Charlie Sheen:  You mean the open bar, right?
  Voice of Emilio Estevez: Sure.
