A doctor and a ninja

Take a look at that picture. Study it carefully and let it sink in for a moment. It looks like a poster for a eighties movie, doesn't it? A cheesetacular of epic proportions, monument to the vulgar self-indulgence of a vast directorial ego, the script scrawled in lipstick on a napkin soaked with whisky and cocaine.
In other words it looks fucking marvelous. The movie alas, only exists within my fevered imagination, but the adventures of Doctor McNinja are real enough. Just in comic form.
Its got pirates, ninjas, Mexicans and dinosaurs. Yeah, say it with me, di-no-saurs.
Surely now your interest is piqued? No? Well get this, not only is he a doctor and a ninja, he punches a snake in the face. Bitchin.
