This one hurts. I grew up on the Cosby Show. That a Different World were the only shows me and the rest of my family sat down and watched together. Thursday nites were special as kid. He was everybody’s big brother. Theo was the best character on the Cosby Show as far as development. I still watch the reruns on TV One from time to time. Outside of tv he always came across as a grounded positive breh. RIP
