The perfect friendship. My real life best friend sometimes makes sure I get a huge takeaway cos he knows it makes me happy and it always reminds me of this sequence. In it, Declan vows to only eat Krusty Burgers for one entire month, to show the bad effects of this unhealthy food. Given that in 12 days he gained 20 pounds, and saying that a month is around 30 days, in the remaining 18 days he must have gained around 28 pounds in minimum, making him at least 48 pounds heavier than before. However he looks to have gained much more than 20 pounds, especially since he became morbidly obese, and to be so you must be at least a pounds heavier than your ideal weight.
