It's a guy thing

It's a guy thing I know
They always have to show
How smart they are: how strong
How much weight they can throw
Picking up those heavy dumb-bells
Showing off in front of their mates!
My dad an old set of train wheels
From one of those little trains
Like puffing billy: child size
Every day after working hard
They'd all go out into that yard
Showing off their muscles: bared
Lifting them up as many times
As they thought they could safely do
I'm telling you: they all vied
To be the toughest: to be the best
Showing off in front off all the rest
All those macho guys: picked them up
Tossed them down: showed off heaps
Each trying to be the biggest clown!
