Author's Note: Please don't attack me in the comments because of the Timeless Child. I also hate it, but RTD and Steven Moffat recently revealed that the Doctor's life cycle will end at the 45th regeneration (46th if you count the War Doctor). The 45th Doctor was Dr. Moon from The Silence in the Library, go search in Google, it's true! Anyway, enjoy!
For one the journey had just begun
Old but young his time to come
But soon enough the clock struck two
The face must change the music must too
So two began
And played it cool
To some extent he was a fool
But time it waits
For no one now
The clock ticked on to three and how
A dandy time
Spent three in time
But the hour of four was soon to chime
The longest hour was spent at four
But soon enough the clock crept lower
The dance of four began to jive
Passing the floor from four to five
Five began with great aplomb
But time is like a ticking bomb
For five the times they went too fast
Soon six was blasting from the past
Six was fresh and played it well
But didn't hear the ringing bell
The chime that brought it to an end
Signalled seven to start it all again
Dear seven
He gave his all for what
The Time Lords time
It did just stop
The bell did toll
For eight once more
But not for long
In Gallifreyan lore
Like hands of ice
That were frozen in time
But the clock stopped ticking
Through the war
The long, long Time War
Which made the course of Gallifrey
Turn for the worse
But changed for the better
And redeemed himself for a better life
The clock thawed once more
And struck number nine
So short was the time
That the clock struck on nine
The adventures were cut short In space and time
But the clock carried on
With a tick and a tock
And soon it was striking
Upon ten o'clock
The tenth hour was long
With a rich honest glow
But tens time was up
He just didn't want to go
But time waits for no man
Old one or young
And ten became eleven
The final countdown begun
And now its time for one last bow
Like all your other selves
Elevens hour is over now
The clock is striking twelves
So in a flash
Eleven became twelve
He was old, yet strong
Menacing, yet forgiving
Spent thousands of years
Breaking the wall
But his time came
He refused to regenerate…
Twice
Yet he accepted his fate twice
He remembered to always be kind
Twelve passed the baton to thirteen
Brighter, curious, and caring
But thirteen was forever doomed
The grandparent of the Unearthly Child
Was the Timeless Child
