I had a dream where someone farted at a bookstore

I had another funny dream last night.

In this dream, I visited some bookstore and buyed a book about Usenet from 1990. The store had an area in the back where people could sit down and have coffee, juice, and bagels. When I was back there, someone farted really loud. A bunch of very studious college students who were sitting at the tables burst out laughing.

Then, when the laughter was dying down, some older guy went, "It wasn't me," just like in the song.
