Cigarette lighters.

It's a bit cheesy. But I know a lot of people (including myself) that tear through cigarettes on a daily basis. Just having that reminder out there (to do an RC) every time you light up would be handy. Plus it might be a good way to attract more people who are interested in LDing to this site?

I dunno. Maybe it's silly. But silly has worked in the past.
