Muffin Man (2003)

Muffin Man is a "Mockumentary" of the downfall of the human species due to our social excesses (mostly over-eating). Thousands of years in the future, anthropologists from a distant galaxy are studying the ancient planet, Earth. Presented as a history lesson, the story follows the evolution of the human race from Homo Sapiens (Modern Man) to Homo Twinkus (also known as ... "Muffin Man"), while simultaneously interweaving an age-old love story: Boy meets girl. Boy falls in love with girl. Girl's abusive ex-boyfriend tries to steal girl back. Boy fights ex-boyfriend and wins his love's heart. Boy has ill-fated encounter with one too many donuts.
