The Boy Who Wouldn’t Stop Burping

The Boy let out a dreadful burp, 
At the breakfast table,
His stay over friend, not to be outdone,
Let out a bigger one.
Then they entered a weird test,
Who could give out, the biggest and best.
Granny then entered the room.
She gave a serious warning,
That into toads, they could be turning.
The boys said, they didn’t care,
A moment later, two toads not boys,
Were sitting there.
