If Mayweather were to lose?

I would find it quite funny and appropriate for him to go to Germany for instance and get robbed by decision. As far as I see it he lost the first Castillo fight but Castillo was robbed and Floyd still had that zero on his record,its a paper zero. I would therefore find it fitting for his record on paper to show a loss despite him winning the fight. All he cares about is his paper record,not his fans etc so I think that would devastate him more than losing by KO,and lets face it,Floyd is a horrible human being a bit of karma is about due to bring him back to reality.
