Flying Raijin Style (Tobirama VS. Minato)

There was a great hokage who 
Was a genius - so much so 
He figured out the secret 
To teleportation, although 
It took a lifetime to perform 

Then there was another hokage 
The one after the next one 
Meaning he was the fourth 
Who studied his technique 
& figured out how to teleport 
In just a fraction of that time 

Clearly this new way be better 
Because you can actually use it 
While alive, but 2nd's fanboys 
Refuse to use the new through 
Meaning they are still stuck 
In the same place as number 2
