Most unintentionally funny shows of all time?

As much as I loved Dark Shadows during its first run, I laughed when I saw it years later in reruns. Barnabas never appeared in one episode when he didn't fumble with his lines. Grayson Hall, in all her multiple roles was always mugging ridiculously. Quentin's perpetually cynical demeanor was hammy as hell. Apart from the acting quirks, technical glitches were often ignored. Stage technicians would wander onto the set occasionally. One episode showed Joan Bennett being pestered by a fly buzzing around her face while she was trying to recite her lines. For some reason they never tried to remove any continuity errors. As a child, I never even noticed but years later I couldn't help laughing at the mistakes.
