The mongrel is a happy dog

Not restricted in character
Of his thoughbred parents
Always a friendy dog
And the nation's favourite pet.

A thoughbred may cost more
And is usually an assessory
Of a proud big egoed human,
The thoughbred has moods,
Requires a lot of attention
Whilst the mongrel is a good friend.

Amongst the human kind,
Mongrel people exist
And like the doggy kind,
Are your best friends.
