The greatest fart ever dropped on a populated area. It was so stinky that it killed over 200,000 people. It was made after death went to Taco Bell back in ‘45 and took a beam and cheese burrito. It was dropped on Nagasaki and ended WWII with the biggest boom at the time.
Person A: “Dude it smells like shit hear what happened?”
Person B: The US just dropped Fat man on Nagasaki if you go there you’ll die from the stink.”

An extremely full colostomy bag .. (after the Nagasaki Bomb)
My colostomy bag filled up so much last night, I woke up with the biggest Fat Man. If that thing exploded the shit would really hit the fan.
