Does anyone know what TV sitcom had the black guy allways climbing in a kitchen window of someone's apartment, sitting at the table and when asked what he is doing says "makin me a sammich"?

MARTIN... was up was up wasupppp!!
I loved that show, I used to watch it all the time.
He would come in through the living room window, I'm pretty sure he was called Brotha man.

I love using the word Sammich!
