Tax attorneys usually aren't known for their sense of humor, but Archie Parnell, the Democratic candidate who is running to replace Republican Mick Mulvaney in Congress, has released an ad highlighting his lighter side. 

The Sumter businessman and first time candidate released an online ad Tuesday spoofing the Netflix fictional political drama "House of Cards," which released its fifth season the same day. 

What's the connection? The show features Frank Underwood, a ruthless and (spoiler alert) murderous politician, who held South Carolina's 5th District seat that Parnell and his Republican opponent Ralph Norman are seeking to fill. (And like Parnell, Underwood is a Democrat.) 

The comical ad includes the show's memorable theme music, reproductions of the dramatic soliloquies that actor Kevin Spacey delivers in the series and some of the character's most memorable lines. 

"Never slap a man chewing tobacco." 

"Shake with your right hand, but hold a rock with your left." 

"Whenever you get someone on the ropes, you throw a right to the gut and a left hook to the jaw." 

"Even Achilles was only as strong as his heel." 

Already, the ad is getting attention — including one that led to an unexpected endorsement for the Democrat.

Michael Kelly, the actor who plays Doug Stamper on the series, tweeted Parnell's ad. In the political drama, Stamper is Underwood's White House chief of staff and former director of strategy.

"Ok, it's official I love this guy," Kelly tweeted with the hashtags #flipthe5th, #flipthePeach, #houseofcards.

But Parnell, who sports a resume as a former congressional staffer and business official with Goldman Sachs and Exxon Mobil, also took the opportunity to take a few shots at President Donald Trump, whose new administration has struggled under the weight of an ongoing investigation into his campaign's ties to Russia. 

"The President of the United States fired the FBI director? That actually happened. It's not on the show," Parnell says after taking a spin on Frank Underwood's rowing machine. 

"Donald Trump shared classified information with the Russians inside the Oval Office," Parnell adds later. "Yep. That's a thing, too." 

The ad finishes by stating, "Archie Parnell is no Frank Underwood, and Washington shouldn't actually be like House of Cards."
