The television show you might be referring to is "T and T" (also known as "Tropical Heat"). It aired in the early 1990s and featured a male and a female detective. However, there is no character named Wednesday or Tuesday in the show, so the reference to a specific day as a character name is unclear. Additionally, there is no known connection to a "tornado thing that did math."
