I love the idea of Rodney being the crude one, for a change!

*g* I like the idea that John defaults (as we all do, I suppose) to dealing with the kids the way he was raised, especially when he's caught off-guard like this. Rodney, on the other hand, probably feels it's his duty to undermine John's uptight techniques at every turn. Plus, boys. You know. Farts are hilarious, etc. (Not that I believe that. *coughs*)
