Thanks Buzzfeed!

Jose kinda has that kind of b.s. going here that makes you wonder....could this dude be right? I mean...it's sort of seems like it makes sense! But then you remember that it's Jose Canseco and that ball he took off the head that went over the fence was probably one of many shots to the nugget that has rendered him into a sort of slightly more intelligent Frankenstein. Good Stuff from the mind of Jose!
