That's great advice and oddly enough, I hadn't thought to put the humor there (when humor abounds in our house). Actually, I read your post earlier and during dinner an opportunity to put it into practice came up. It went something like this:
DS: Dad didn't really like the new recipe you tried.
Me: Yeah, I know. I didn't care for it either...didn't turn out quite like I'd hoped. Guess I'm no good at anything since I didn't get that right tonight...
DS (deadpan and w/out missing a beat): Guess not. You should join my party.
It was hilarious and I had to laugh. Of course, he picked up on what I was doing right away....the stinker!
