The Doctor 3 (Doctor Who? 100)
From Tardis Wiki, the free Doctor Who reference
In a "what if" scenario, one incarnation of the Doctor was portrayed by Ronald Reagan. He had recently undergone a partial regeneration before exiting his TARDIS that he had landed in a desert. He claimed that he had only regenerated his hair and prepared to undergo the full process. (NOTVALID: Doctor Who? 100)
