I don't think you're going to be getting 20+ entries from me this go-round.  But you're welcome to whatever emerges!  This is a skit on one of Percy French's better known songs ...

Oh Mary this racin's a wonderful sight
These lassies wear gear that is ever so tight
Whenever they're out for a run roun' the track
Their runnin' shorts near disappear up their crack
The 400 metres, the sprint or the mile
I don't watch the race, I'm transfixed by the style
Of those lycra-clad lassies I watch on TV
From the place where the dark Mournes sweep down to the sea

They strain at the blocks with their arse in the air
And I can't tear my eyes of their taut derrieres
The local girls' hips are all tweedy and wide
Not like those young athletes' slender backsides
I got satellite now and I neave l'ave home
I've no rayson to wander, no rayson to roam
They beam in those young honeys from morning till eve
To the place where the dark Mournes sweep down to the sea

Oh by Jesus above I'm very impressed
With the way those athletic young ladies are dressed
And me an oul' lech with a wanderin' eye
With a taste for a quick flash of rump or of thigh
It's better than Playboy or one of those mags
Where the hussies strip off and then striddle their legs
It's a cause for confession, oh Mary mo chroi
In this place where the dark Mournes sweep down to the sea
