Feeling dated

Conversation in the lab:

Andrew: "Isn't there some song that the CIA plays to prisoners to get them to talk?"

Arjun: "Probably some crazy pop songs. There was this one from grad school that used to play on the radio in the lab that drove me nuts. I can't remember it, though."

Olivia: "What was it? I want to know–I feel like it would date you."

Sara: "Was it by John Lennon?"

Ouch.
