A former Deutsche Bank executive testified this week that the German financial behemoth only agreed to make massive loans to Donald Trump because of Trump’s vast personal fortune. The problem? The bank apparently thought, based at least partly on financial statements provided by Trump, that he was far wealthier than he really was.
The story goes that they were out drinking, doing weird impressions, and toad said (in a Donald duck voice) "hey, I'm Donald Dick!" Obviously Mario and Luigi refused to let it go, and that's been his nickname ever since. It's also why D.K. won't drink with them anymore, Mario is a mean drunk.
