Tyler Marcum filmed a video of himself dancing to the Dixie Chicks' cover of Fleetwood Mac's "Landslide" in 2003 when he was 20 years old.
About to turn 30, Marcum filmed another video of himself dancing to the same tune and edited the two videos together, reports MSN.com.
For reasons unknown, Marcum performed the dances in his underwear.
"When I was 20 I filmed an interpretive dance to Dixie Chicks' "Landslide" in my college bedroom - and in my underwear. I turn 30 in a week and couldn't think of a better homage to my twenties than a sensible mashup," Marcum wrote on YouTube, where his video has over 100,000 views since May 14.
