Lets write a Limerick, one line at a time.

[klondike]

Bella went to town on the tram
She hoped the conductor would be Sam
He wore his trousers very tight
Bella always admired the sight
And it didn't hurt that he called her ma'am

Bella groaned - it was Ted in charge
His trousers were far too large

[Ruthio]

Bella groaned - it was Ted in charge
His trousers were far too large
She felt very glum

[GrannyMac]

Bella groaned - it was Ted in charge
His trousers were far too large
She felt very glum
At the sight of his bum 
It was almost the size of a barge.

[GrannyMac]

The slimming class was going well
Joan, lost three stones and you could tell

[klondike]

The slimming class was going well
Joan, lost three stones and you could tell
All her clothes hung slack and baggy
But inside them was no longer saggy
Off to Primark. Check what they sell.

Three hundred quids worth in her bag

[GrannyMac]

Three hundred quids worth in her bag
But she'd forgotten - security tags
The siren sounded loud and shrill

[klondike]

Three hundred quids worth in her bag
But she'd forgotten - security tags
The siren sounded loud and shrill
Would they call for the Old  Bill
Or would it just be a finger wag

She decided not to take the chance
Her new fit legs lead them a dance
