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.

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.”
