I guess that sheds a little light on it, Scott!
Just curious to how the conversation would have turned out had I said, "Yeah I've got a candle lit right here in front of me!"
I haven't heard the 'I'll buy you the DVD' expression before, but that would make sense I guess. However the context he used it in doesn't really.
So, assuming he meant that he's either a) Going to buy me the DVD to show me how to light a candle or b) The DVD of how you make your brain work - It doesn't really all fit together, just sounds kind of stupid.
It's not got to me, I just want to know what the fook he was referencing too.
