Tommy Chong as Leo Chingkwake was one of the funniest characters on That 70s Show who consistently delivered some of the series’ most memorable quotes. Across eight seasons, Chong turned Leo from a one-note stoner character into an engaging and insightful father figure for Steven Hyde and, at times, an oddly poetic speaker of philosophical wisdom. Chong was perfectly cast as the aging hippie Leo because, as one-half of the cult stoner comedy duo Cheech and Chong, he was already an integral part of 1970s pop culture.
