Gibbons, pigs and lions

There once were some horrible gibbons
Who enjoyed tearing people to ribbons
They went through a bad patch
When they met with their match
Having stumbled upon Bernard Cribbins.

Quite suddenly panic ensued
When the wings from the pigs came unglued
They descended together
Like birds without feathers
With numerous greenness endued.

A signwriter outside a pub
Was hit by a man with a club.
"It's just that I've seen
You need more space between
The words 'Lion' and 'And' and 'And' and 'Cub'."
