My Theory on Time and Space (Mr Heidegger)

I haven't enough time to work out your 'time'  Mr Heidegger
I'm too busy and it bores me so
Isn't it just a waste of my grey-cells 'time'  

Mr Heidegger
and what little grey cells I have 

do run slow
Thinking about what 'time' really is 

is a waste of time 

Mr Heidegger

I'm really not sure I should know
The 'time' is what the BBC say the time is 

Mr Heidegger
Anymore 

and my brain 

will overflow!
