What a Relief!

From London to Manchester in a car
After a large cup of coffee from the bar
That was a mistake, a big one by far
An hour passes progressing on the tar

Oh Hell, I need to pee!
OMG I am now in a sweat
Somehow I mustn't get wet
At last a Motorway stop I see

Rush to the Loo all a quiver
Get ready to stand and deliver
Oh! Oh! the huge relief
It really does beggar belief!
