He was just using some sarcasm from a previous incident where Doggy Kruger made multiple cold remarks in the Eddie Guerreo passing away thread.(Which were very similar) Which really upset most of the posters in that thread and no mod/admin really stepped in a-la Keith "JC" Hayward to try and stop things.
If Bolt were serious he'd say a couple kind words but he just didn't want to miss the opportunity of putting the shoe on the other foot. He didn't actually mean that.
As for myself, it's sad to lose an actor who became such a strong icon. I remember his role in the Karate Kid films, but I also remember him back when he was on Happy Days. He will be missed.
