Rodney Dangerfield passed away in 2004, but his widow Joan still remembers him by the bottle of his sweat preserved in her refrigerator.

Joan explained to The Hollywood Reporter how she and Dangerfield got the idea for keeping her husband's sweat in the first place. "I discovered that Elvis had a handkerchief that was apparently stained with his sweat and it went for a lot of money," she said. "So Rodney had a 'eureka' moment. He said, 'I sweat more than anybody! My sweat has to be as good as Elvis' sweat, right?'"

Joan then began collecting hundreds of perfume-sample bottles to collect her husband's sweat in, collecting inches of perspiration at a time. After selling some of the bottles, the MGM Grand Hotel & Casino forced the couple to stop their unique business due to insurance issues.

But Joan still keeps his sweat in a Tupperware container in the refrigerator. "It means a lot to me," she said. "I do know how hard he worked to make people laugh."

On Friday, Nov. 22, which would have been Dangerfield's 92nd birthday, Joan revealed , a website dedicated to her late husband. The site contains handwritten jokes, photos of Dangerfield and other information about the man who invented the catchphrase "I don't get no respect."
