MY GRANDFATHER INVENTED

 

My grandfather invented,

And you might well scoff,

The cold air balloon, well

It never really took off

THE INVENTOR OF THE ALLEN KEY

 

The inventor of the Allen key

Made nothing off it

Despite the fact that

It certainly turned a profit

HERE IS AN INTERESTING FACT

 

Here is an interesting fact

Which should come as no surprise

The inventor of the humble

Door knocker won the No-bell prize

THE RIGHT QUESTION

 

“You probably get this quite a lot I expect,

So I’ll make it quick and not prolong,

Aren’t you the chap who invented Tippex?,

You are, are you not; correct me if I’m wrong”
