A group of people where I used to work would hold a Chili/Halloween party. I always had to tone down my Willy Chili for the poor people; I think rather than using three blended-up habaneros, I substituted cayenne instead. Never had quite the same kick, but people still always seemed afraid to indulge in it.
(The "real" recipe also had cayenne in it; the cayenne for the up-front burn, the habanero for the delayed burn.)
What's sad is that of the first ten sites uncovered by Google, only one actually referred to the cayenne pepper - there was a communications company, something about the islands, and some other miscellany.
