He starts buying up BP when everyone, and their mother, is bashing the hell out of the name. (He was one of the reasons I bought BP.)
Then some guy writes an article on why he was wrong in Seekingalpha.com, titled 'Why Whitney Tilson is Wrong About BP'. I rarely expect one of the big-boys to respond to such articles, but he is human after all.
Tilson responds in the comments section pretty much saying, in the most elegant and political way: stop being scared bitches, under stand the real reasons cause you all got it wrong from day one.
(Unfortunately I didn't participate in BP's ascent due to other risk/reward opportunities, to which treated me very nicely. Hence no regrets.)
