Fan Casting Brain Smartz (2011)

Life is (somewhat) peaceful for Einstein back in Princeton. He basks in the afterglow of his "dinosaur discovery" (mostly fabricated to protect Bernardo's secret), enjoys Time Displacement's caveman cooking show ("Prehistoric Eats with TD"), and even tolerates Bernardo's existential moping in his backyard.

Suddenly, their peace is shattered by the arrival of General Bantu, a charismatic but demanding African leader. General Bantu, having heard rumors of Einstein's genius (and a healthy dose of exaggeration from Time Displacement's book tour), declares war unless Einstein builds him the ultimate weapon: a flying chariot.
