Turns Out That Sweet Little Mary Ann...

...was one savvy piece of farm-fed ass:

Wells was married to talent agent Larry Rosen when she was hired for the Gilligan cast, and it was Rosen who noted the clause in her contract (which was standard at the time) that limited her to collecting residuals only the first five times any episode re-ran after its original airing. Rosen told Wells that if the series was a success, this clause could cost her a lot of money. Wells was the only castaway who asked for an amendment to that residual clause in her contract, and the producers granted it, never thinking the series would be on the air 40 years later. As a result, Sherwood Schwartz and Dawn Wells are the only two folks connected with the show who still receive money from it.

Nom$ nom$ nom$!!!!
