My mam has just spammed my Facebook wall with a load of Dr Who trailers. She knows I haven't even watched it since Tennant left.
Over Christmas my dad made me sit and ask him EVERY single question in his Star Wars trivia card set thing, just to show me he would get them all right - he did. It was the most tedious day of all time.
I clearly had no chance of not becoming a nerd with this upbringing.
So, how nerdy are your parents?
