When we were in India we saw an advert on the back of a magazine for a ruler.
"guy 1: hey, what's your favourite hobby?
guy 2: answering stupid questions,
guy 1: are you being serious?!
guy 2: no, I'm sirious!
You can't always get a straight answer, but now you can get a straight line!"
I laughed so much I wrote down the email address to contact them to tell them how fucking awesome their advert was. ...Never got round to it though..
