"run fatboy run" ~ Whit "I can lose weight but you'll always be an asshole" ~ Dennis (exchange between Whit and Dennis during the marathon) Whit is the main love rival of the romantic comedy "Run Fatboy Run" and is thus the closest thing the movie has to an antagonist - though for much of the movie he is a jerk at worst, however near the end he does arguably cross the line and recieves karmatic retribution as a result.
