Once upon a time, Dr. Horrible was in his lab, still depressed over the death of the love of his life, Penny. He had cried so much, it started a mass flood in Japan where a sexy octopus lived, but that's a different story. "Wait," Dr. Horrible said to himself. "If I go back in time, I can stop Penny from dying, and I can kill Captain Hammer instead!" So he began to build a time machine, luckily there was a guide on how to make time machines on the site ehow, so it only took him two hours.

"Now I'm off to the past!" Dr. Horrible declared as he stepped into his time-machine.

As he was travelling through time, he hit something. It was Bill and Ted's time machine, which just so happened to be travelling the same time as Dr. Horrible. The collision wound up sending Dr. Horrible off course through time.

When the machine came to a stop, Dr. Horrible looked to see he was at the presidential inauguration of Howard Taft. "Balls," Dr. Horrible said. "It takes three hours until I can use the machine again." He thought about how he could use his time wisely, and thought that if he overtook the government using his modern technology, he could control the world. He took out his freeze ray and while Mr. Taft was speaking, Dr. Horrible said "Freeze, Mr. Taft!" as he fired the ray.

What Dr. Horrible did not know was that Howard Taft is immune to freeze rays, so Mr. Taft was angry. "You dare intrude on my inauguration?" Taft screamed as Dr. Horrible shivered in fear. "I challenge you to…" Taft said as Dr. Horrible reached for his death ray. "A rock off!"

"What?" Dr. Horrible asked, wondering why Howard Taft would challenge him to a rock off.

"You heard me, a rock off! A true test of skill!"

"Very well," Dr. Horrible agreed. "I will allow you to go first."

Taft then proceeded to pull out an electric guitar and began to play the most immense cover of the song "Rock 'n Roll McDonalds". Dr. Horrible was frightened. Never had he heard such an amazing cover of a song before, there was not one dry eye in the audience. Though things seemed grim for Dr. Horrible, he was persistant, so he took out a set of bongos, and began to play a cover of "Chocolate Rain". The performance was too much for Taft to handle, so he collapsed in defeat, allowing Dr. Horrible to take control of America.

As he was approaching the stage to accept his flawless victory, a truck suddenly flew at his head. Who could have thrown an entire truck? Why it was none other than Captain Hammer, who came just in time. Dr. Horrible had been defeated by the Hammer once more. Captain Hammer picked Mr. Taft up, as Dr. Horrible limped back to his time machine, and treated Mr. Taft to a trip to the local truck wash.

THE END.
