Back when Tyler Marcum was 20, he acted a lot like... well, a 20-year-old. To celebrate finally leaving his teenage years behind, Marcum recorded a video of himself dancing to Dixie Chicks' 'Landslide' in his underwear. Fast-forward 10 years later, and Marcum is celebrating 30. As an homage to his young self, the hilarious Dixie Chicks fan celebrated by remaking the video from his 20th birthday.

Marcum's 'Landslide' performance isn't your run-of-the-mill 'selfie' video of someone singing into a hairbrush or strumming on a guitar. Ten years ago, the hilarious 20-year-old choreographed an interpretive dance to the emotional love ballad, flailing his arms around and acting out every word to the song.

Of course, Marcum perfected every movement to demonstrate the lyrics about climbing a mountain and experiencing change ... while wearing nothing but his skivvies.

The best part is, the now 30-year-old country music fan doesn't look much different than his 20-year-old self. He remade his original music video by redoing the dance and creating one split-screen clip of himself doing the same dance 10 years apart. It takes a few seconds to figure out which Marcum is the 30-year-old!

The funny man might wear the same size pants -- and the same type of underwear -- as he did 10 years ago, but his dance moves have definitely evolved. His latest video reveals that his hip shakes and booty dances are way better this time around. It's safe to say he gets better with age!
