Marigolds

It's springtime in the Canadian Rockies, and the marigolds are in bloom. The only problem is that Dudley Do-Right of the Mounties is allergic to marigolds. Once Snidley Whiplash finds this out, he plants marigolds on his jacket and hat, making him invincible to Dudley. Eventually they come up with a plan to beat him, and Nell plants crab grass on the marigold suit, killing the marigolds. But of course, Snidley escapes in the end. (And we find that Inspector Fenwick is allergic to crab grass.)

This show was a satire of the old-time western melodramas, featured the title character as an inept Canadian Mountie who served under the kind and patient Inspector Fenwick. Do-Right spent most of his time rescuing Fenwick's daughter, Nell, from the evil clutches of the classic villain Snidely Whiplash. A bizarre love triangle between Nell, Do-Right, and his horse (named Horse) also provided for laughs.

Dudley Do-Right spun off into his own series on ABC for a year in 1969, but the show was primarily repeats of these original episodes.
