Rationale Puns

I'm helping with dinner in the kitchen when a dog food commercial comes on. It was literally a 5 minute long ad telling about how generic dog food wasn't good for your dog and how I should buy their product. I'm scrubbing a dish, shaking my head, silently hoping someone changes the channel to something more entertaining and my dad looks up and exclaims "I don't know what the hell they're talking about!" I quickly look over at him waiting to hear his rationale over why he's so upset. He looks back slyly and says, "...tastes fine to me." I died laughing.
