exercising some control

I've got a dog he's like a two ton frog
I call him some control
yesterday I took him for his walkies in the park
he's a beautiful thundering soul
at first he never took a fancy to any one wondering by
until a big fat cop came ito his sights and he had to know the reason why
so he took a little piece out of the gentlemans leg
and the gentleman was sore supprised
so limping up to me
he whispered quietly
'what are you playing at?'
'I'm exercising some control.. oh oh '
Sorry, can't remember all of second verse _ Mike.
