A few things I've considered.

What if sex offenders used the sex offender registry as a dating site?

What if there was a Dexter of sex offenders? [I guess he would be Sexter]
(for those of you unfamiliar with Dexter, he's a serial killer who kills serial killers)


So I visited a guy's house. He had a lot of blades. I thought to myself, that's sort of interesting.
