Rhubarb and Custard

Made quite a pair,

Lounging in Bowl

Side by side.

 

Custard said to Rhubarb,

"Let's play a little game.

Let's swap the last letters

Of both of our names."

"Good idea,"said Rhubarb,

"But I'll only agree to do it

If you stop smothering me!"

 

So after a bit of banter

And a heated exchange,

"Rhubarb" and "Custard"

Became  "Rhubard" and "Custarb",

But "Bowl"...

...well, he stayed the same.
