Rowf, Rowf

Two pieces of doggerel on my last day, one by Elise and one by me:

There once was a man from Hancock
Whose own job he would constantly mock
He said with a frown as he sat back down
Please fire me or knock my block ock!

There once was a man from Hancock
Whose own job he would constantly mock
But he quickly acquired one he'd always desired
While his colleagues cried out "What a crock!"

Can you tell which one's which?
