Carl’s Jr. and Hardee’s say rivals’ food tastes like ‘Diesel and Sadness’ in Campaign for $5 All-Star Meals.

Carl’s Jr. and Hardee’s humorously troll competitors in new ads for the chains’ $5 All-Star meals.

In spots that play heavily on value, the chains take aim at fast-food rivals like Subway–one spot, seen here, shows a guy in his basement guillotining what looks suspiciously like a $5 dollar sandwich from the sandwich seller.

Another ad talks about “playing dollar-menu bingo” and ending up with an un-appetizing looking “fish sandwich” while a third spot shows a man burning his mouth on a gas stastion burrito which “tastes like diesel and sadness.”
