Yeah, I think the old man still has it in him. Example:
There was an episode when Paul Sr. had won an Ebay auction for a late 60's metric choppper. All the younger cats in the shop gave him a ribbing for having any interest in (their opinion) a goofy looking old bike. Senior didn't care, he said the bike spoke to him when he saw it, and he was going to ride it. It *was* pretty cool looking.
