Rejection line
I've been listening to clips from Wiretap (which I HIGHLY recommend!) with Jonathan Goldstein (a frequent This American Life contributor). There was one with a conversation with a "rejection specialist" from the Rejection Line, a phone number you give to people you really don't want to talk to again. So I looked up various rejection hotlines wondering if any of them addressed the prevalence of text messaging in dating communication. It doesn't look like it. That's a market that needs to be tapped. But anyway, I found this which is a phone number you can give out that rickrolls the caller. Ah rickrolls. How I love them.
