- Reel Feels – The Chiodo Bros. are well known for their work in writing, directing and doing all the special fx in 1988’s “Killer Klowns from Outer Space”. But it was just three years later in 1991, that those same molds for the Killer Klowns would be seen again, but altered for another purpose in the classic children’s comedy “Ernest Scared Stupid” You may never have guessed it, but the same molds and extra pieces not used in 1988’s “Killer Klowns from Outer Space” allowed for the Chiodo Brothers to once again use their talent for creating the nightmarish and gross looking trolls that Jim Varney went head to head with as the beloved, if not bumbling, underdog hero Ernest P. Worrell.

Socrates lost that trail and was sentenced to death!
- Estelle Getty, who played Sophia in The Golden Girls, was one year *younger than Bea Arthur, who played her daughter Dorothy, so big props to the makeup and costuming folks.

- Ballsy History – At the beginning of the 19th century, trading Chinese goods such as tea, silks, and porcelain was extremely lucrative for Britain. However, they would not buy British products in return and only wanted to sell their goods in exchange for silver. In order to stop this, the East India Company and others began to smuggle Indian opium into China illegally—and they demanded payment in silver which moved the balance back to the way Britian wanted it. The silver, in turn, was then used to buy tea and other goods. By 1839, opium sales to China covered the entire tea trade. When the first Opium War began, it was in large part thanks to tea.
