The Republican National Convention's surprise speaker Thursday night was none other than Hollywood heavyweight Clint Eastwood, who had one message for the Democratic party come November, 2012: "Go ahead, make my day."

The 82-year-old stepped on the stage at the GOP convention in Tampa, Florida prior to Mitt Romney's acceptance of his party's official nomination, and the Oscar-winner rallied for the cause with all the fire you'd expect from Dirty Harry.

Throughout his ten minutes onstage, Eastwood directed his no-nonsense attitude at President Obama, who he mock-conversed with via an empty chair.

"I've got Mr. Obama sitting here… and … I was going to ask him a couple of questions," he began. "I remember three and a half years ago, when Mr. Obama won the election. And though I was not a big supporter, I was watching that night when he was having that thing and they were talking about hope and change and they were talking about, yes we can, and it was dark outdoors, and it was nice, and people were lighting candles…Everybody is crying, Oprah was crying… I was even crying. And then finally -- and I haven't cried that hard since I found out that there are 23 million unemployed people in this country…. So, Mr. President, how do you handle promises that you have made when you were running for election, and how do you handle them? "

While at first hesitant to use his now-famous quote, the crowd egged him on and he closed the speech with the infamous words of his most iconic character.

He said, "I'll start it and you finish it. Go ahead…", to which the audience replied, "Make my day."

Not long after Eastwood wrapped, a Twitter account was inspired by the actor's conversation with the chair representing Mr. Obama, playfully handled @invisibleObama, which quickly grew to gain tens of thousands of followers since.
