Lets write a Limerick, one line at a time.

[Mups]

A tango, a quickstep, they sailed across the floor
Ladies choice? Beryl was keen to dance some more 
They whizzed round the floor at a good pace
With both of them having a smile on their face
Until Percy waltzed out of the door.


"Where are we going?  It's cold out here"
Said Beryl as she leaned into Percy's ear

[Ruthio]

Where are we going?  It's cold out here"
Said Beryl as she leaned into Percy's ear
But Perry needed a wee

[Mups]

Where are we going?  It's cold out here"
Said Beryl as she leaned into Percy's ear
But Perry needed a wee

Has Percy had a name change?   

[klondike]

Where are we going?  It's cold out here"
Said Beryl as she leaned into Percy's ear
But Perry needed a wee
Which lav to use (s)he'll have to see
