Every once in awhile, the reality shows will cross over. You'll have one prominent member of a reality show show up on some other reality show. It's like one big, happy inbred family. Ricky Croft, who was the manager of Key West's mystic tan store, showed up on America's Most Smartest Model.
Although this isn't really news, Croft was hawking his mystic tan system and showed up for no particular reason whatsoever. The models won a challenge in which they were able to use the machine, but it seemed like the models didn't need direction to use it. Croft was just there to introduce the machines.
If you remember, Croft actually got a lot of criticism for calling himself the "eighth roommate" and starting a blog posting small details amongst the cast. Looks like he's moved on to other avenues.
