According to TMZ:
Kato Kaelin said something pretty interesting on his way out of Hyde last night. Yes my friends, Kato actually got into Hyde and maybe that's the lead.
But on his way out, someone stopped the man who was in O.J. Simpson's guesthouse the night Simpson banged into the air conditioner and dropped his murder glove.
Kaelin was asked about Simpson's disgusting book, "If I Did It." His response -- "What do you mean 'if'?"
