Where’s the tin-opener?
In the drawer. Why?
I need to open a tin!
Because I need the food inside!
To stay alive!
Why do you need to stay alive?
It’s a biological imperative!
Why is it a biological imperative?
Because I need to stay alive to procreate!
Why do you need to procreate?
It’s a biological imperative! It’s the purpose of life!
So the answer to Life, the Universe and Everything is a tin-opener?
(Bloody stupid question…)
