Lets write a Limerick, one line at a time.

[klondike]

She turned one into a donkey, another into a toad
She cackled wildly as she set off down the road 
Then her lucky black cat fell off her broom
And down a chimney into Reg's living room 
It landed well, it's legs just bowed

Then leapt up all teeth and claws

[GrannyMac]

Then leapt up all teeth and claws
Blood dripping from its jaws
A scary sight, the others ran

[klondike]

Then leapt up all teeth and claws
Blood dripping from its jaws
A scary sight, the others ran
All except old fat Stan
This caused that wild cat to pause

For fat Stan was more than large

[Mups]

For fat Stan was more than large 
He was in fact, a bit like a barge
With hands the size of a dinner plate
The witch's cat didn't know its fate

[GrannyMac]

For fat Stan was more than large
He was in fact, a bit like a barge
With hands the size of a dinner plate
The witch's cat didn't know its fate
It thought the witch was still in charge! 

Fat Stan stomped towards the puss
And said 'leave, don't make a fuss'

[klondike]

Fat Stan stomped towards the puss
And said 'leave, don't make a fuss'
That cat gave Stan one careful look
Gave a miaow and off it took

[Mups]

Fat Stan stomped towards the puss
And said 'leave, don't make a fuss'
That cat gave Stan one careful look
Gave a miaow and off it took
Riding the broomstick gave him a buzz.

While  Bertie was shovelling snow

[klondike]

While  Bertie was shovelling snow
His nose gave off a "Rudolph" glow

[Mups]

While  Bertie was shovelling snow
His nose gave off a "Rudolph" glow
His feet were cold, his hands were numb
Then he suddenly slid over onto his bum

[GrannyMac]

While  Bertie was shovelling snow
His nose gave off a "Rudolph" glow
His feet were cold, his hands were numb
Then he suddenly slid over onto his bum
He gave the neighbours quite a show! 

              *************

His jeans were loose without a belt
He slipped and let out a mighty yelp
His tatty long johns were a sight

[klondike]

His jeans were loose without a belt
He slipped and let out a mighty yelp
His tatty long johns were a sight
Yanking up the jeans with all his might
Begging no-one offered help

Nobody about so grateful for that
He risked a fart and then he spat

[Mups]

Nobody about so grateful for that
He risked a fart and then he spat 
He reached for his spade
And fell over the Snowman he'd made

[klondike]

Nobody about so grateful for that
He risked a fart and then he spat
He reached for his spade
And fell over the Snowman he'd made
Swore and went back to his flat

Doris couldn't help but smile
Bertie had messed up in style
She had the video on her phone

[Mups]

Doris couldn't help but smile
Bertie had messed up in style
She had the video on her phone 
So funny when he tripped over the gnome
