Because Chihuahua's are omnipotent.
Praise the Chihuahua, oh insufficiently equipped humans, and you may find salvation!
Chihuahuas must be what James Brown was singing about in Sex Machine or they wouldn't be able to get stuck in something countless times bigger than the entire dog:
I have seen a Chihuahua knot a donkey in real life.
I don't really understand what exactly was going on or what the owners were thinking, or how this is possible as he would fit inside as a whole easily, but happen it did.
The donkey didn't understand it fully either as it started to run, at top speed, with the dangling dog bouncing back and forth and left and right like a punching ball (really looked like a punching ball).
Now if bitch Naomi got knotted by a Chihuahua the only thing capable of making it better would be Morgan Freeman narrating the procedure.
