First heard of 'Big bang theory' at a carers' center course for parents of autistic children (teens) from other parents who sang it's praises (my child is pre-teen).
Never watched it till lately,watched a few episodes on tv, bought my near as damn it 9 yr old box set & he adores it. Laughs out loud at it. The child who never sleeps before midnight will take himself off to his room to watch it. (still never sleeps before midnight).
Haircuts...like Sheldon. (nightmare doesn't quite compute)
In so many ways - like Sheldon.
Helps in some way I suppose.
