Well, first off he's lying to everyone by saying all he said was "Hah." That doesn't even remotely make sense. Lying seems to be an admission that you know what you did was wrong and you're ashamed of it enough to not want to admit doing it. Also, though, Jays commentators and players both said that they had never in their careers seen someone do that, that it was "bush league," and that the Yankees don't normally play like that. (Glaus said that he had never seen anything like it in 30 years). It doesn't "happen all the time."
I don't really care that much that he did it, but I think lying about it shows he's a pussy.
