More Very Bad No Good Parenting

My elder son Sean has been grounded.  Week one was a total tv blackout, however week two he is allowed more 'educational' type tv.  I loaded up the Netflix instant queue with documentaries and went about my business.  I come back in the lounge to see him watching Tremors 2.  'Seriously my beloved?' I asked.  'Dude, they are Precambrian.'

Now I could have told him to turn it off.  I could have asked him about the Precambrian era.  I could have even asked him why he was calling me 'dude'.  Did I do any of these things?  No.  I said tell me three ways to avoid the worms and three ways to kill them that are not in the film, whilst I make the popcorn.
