Yeah but that thing in the Old and the Restless was a one-time comment. And hilarious in my opinion, and totally random. But they never brought that up again, so I don't think it was really meant to be that significant, just something they threw in there because they thought it was funny.
Besides, early seasons show Gus to be extremely squeamish at the sight of blood and bodies, he regularly gags and runs away etc. I don't think the joke is inconsistent in the first place. It's actually quite typical children's behaviour trying to make a friend do what you'd never dare yourself.
