Fat logic from step-dad, couldn't even respond through laughter. I'm in the car with my step-dad(Fatass), step-brother(Slightly less but still a fatass), mother(Holy shit she's fucking ginormous), and little bro(not fat). So we're going to wash the car and stop at a gas station by this absolutely MASSIVE whale, like this thing was so fat that when it stepped shockwaves rippled through it's body. While pig-mom goes to get her hourly liter of liquid sugar, I'm laughing my ass off at this thing trying to get back into it's car. I'm not even trying to be subtle. So this whale manages to smash itself into the car (Much to the suspensions displeasure) and drives off. At this point me and little bro are fucking dying in the back from laughter and step-pigs are getting visibly red. Suddenly (I shit you not) Step-dad yells "MAYBE SHE HAS A THYROID CONDITION" He's fucking fuming but I legit cannot stop laughing. Little bro is confused so I explain that at most a thyroid condition can cause about ten pounds of weight gain, Pig-dad interjects "NO THATS NOT HOW IT WORKS!" I just straight up laugh and say sure.
