The summer phenomenon that will keep our eyes glued to the tube and our thumbs working overtime on Twitter arrives Wednesday night when "Sharknado 3: Oh Hell No!" debuts on Syfy. Here are five tidbits about the franchise you can use to impress your friends:

1. Songs for the soundtracks of the first two movies were written by Robbie Rist. And while this achievement may be notable itself, Rist achieved his biggest fame at an early age: He played Cousin Oliver, the blond-mopped, bespectacled boy who moved into the Brady household for several episodes at the very end of the final season of "The Brady Bunch."

2. "Sharknado" star Ian Ziering has said that he had major reservations about signing on to the project. But he said yes because he needed to earn enough money to qualify for Screen Actors Guild health insurance for his family.

3. "Sharknado 2: The Second One," which aired on July 30, 2014, was Syfy's biggest original movie, with 3.9 million watching it on TV and, like its 2013 predecessor, absolutely killing it on social media.

4. Among the product tie-ins for "Sharknado 3" are a David Hasselhoff bobblehead (he plays the father of Ziering's character) and an "Archie" comic book.

5. Cameos abound in "3": Penn & Teller, Jerry Springer, "Today" co-hosts Kathie Lee Gifford and Hoda Kotb, Lou Ferrigno, Frankie Muniz, wrestler Chris Jericho, and ex-politicians Michele Bachmann and Anthony Weiner. And, as the U.S. president and vice president: entrepreneur Mark Cuban and political commentator Ann Coulter.
