A Stupid Observation
Birds have cloacas. This means the food goes in the mouth, through the insides, and out the poop shoot. A poop shoot that does not have butt cheeks.
Normally, this wouldn't be noteworthy. But today...
When you or i fart, the flatulence escapes our tooshie tunnel and creates that musical song that can only be sung using the greatest of instruments: our butt flaps. This can be uproariously funny for young you and mildly chuckle-worthy for older you.
However, when your bird has gas, it's fucking hilarious. Watching a bird's butt feathers pfft is the best free entertainment money won't buy.
