To prevent you causing trouble these guidelines I will set

Which you should follow faithfully – your toilet etiquette.

It's always a conundrum that you'll have seen first hand

At which of the urinals you should opt to stand;

Take this formation if you will – there's four urinal loos,

A bloke is stood at Number 1, so which one should you choose?

The obvious one is Number 4 to give him a wide swerve

Consider though what he might think, that you think he's a perve.

So that would leave Pots 2 and 3; you choose the 2nd Pot;

But he might think you're taking a good peep at what he's got;

The answer, then, is Number 3; you'd go for this third stall,

The choice of grown men everywhere, the safest one of all.

But woe betide the foolish bloke who stupidly has gone

And joined that urinating man to share with him Pot 1.
