The other night I went to see the improv duo TJ and Dave. Not only were they hilarious, they described some unforgettable visual images that were stuck in my head upon leaving...one being an eagle carrying an orangutan. I forget what the context was, but when one of them described this occurring, the other asked, "But why?".
So here's my interpretation of that scenario at the bar later that night.
So, TJ and Dave, if you are out there, here is my answer to your question, "But why?" An eagle would carry away an orangutan because they're in outer space, where there are no rules.
