There's the famous thing that the A&R man from the record company is supposed to do: He's supposed to come into the studio and listen to the songs you've been recording and then say 'Guys I don't hear any singles.' And then everybody falls into a terrible depression because you have to write one.
I heard on public radio recently there's a thing called Weed Dating. Singles get together in a garden and weed and then they take turns they keep matching up with other people. Two people will weed down one row and switch over with two other people. It's in Vermont. I don't think I'd be very good at Weed Dating.
