Johnny Knoxville, Ryan Dunn Johnny Knoxville, Ryan Dunn

Although Johnny Knoxville spoke at Ryan Dunn's memorial Wednesday, he says he couldn't convey what his co-star, and friend, meant to him.

"What came out were the mumblings of a man trying his best not to cry," Knoxville wrote on his blog Sunday. "I also didn't get to properly convey what Ryan meant to me. I won't be able to do that here either, but I will try. Here is what I wished I could have told everyone then."

Knoxville wrote that was Dunn funny but could be serious too. "Ryan was a great listener," he said. "If you were having troubles, he was always someone you could go sit down and talk to ... That's why all this is even harder because right now I really need to talk to him but I can't."
