Comedian and actor Blake Clark grew up in Georgia and fought in the Vietnam War before hitting the small screen in the early 1980s in a string of guest starring spots on shows like M*A*S*H, Moonlighting, and St. Elmo's Fire. During this time, he was also featured in comedy specials on HBO, NBC, and ABC. The roles kept pouring in for the gruff-voiced actor, who landed a regular role on Home Improvement in 1994. He played Tim Taylor's friend Harry, who owned the hardware store where Tim spent much time and money. Clark also had recurring roles on The Drew Carey Show, The Jamie Foxx Show, and Boy Meets World (as Shawn's father, Chet). On the big screen, Clark became a favorite of Adam Sandler and was cast in many of his movies, including The Waterboy, Little Nicky, Mr. Deeds, and 50 First Dates. Clark also replaced the late Jim Varney as the voice of Slinky Dog in 2010's Toy Story 3.
