Okay why I am going to answer this question with a serious answer is beyond me but here goes...
They have a lot of fresh fruit and other fibrous food in a different culture that your family may not be used to eating, all that fiber helped clear a path so to speak and probably "cleaned you guys out" and in the process there was more and longer, well...poop.
Simultaneously gags and blows coffee out his nose.
This is still hilarious...after nine months... still funny :P
No doubt Snarky has the answer!
It is a fact that fiber is the 'Clean Out' material people need. If you eat a lot of vegetables, fruit and nuts you will see this come to pass lol, literally.
