WATCH: Man torments sister by lip-syncing through 7-hour road trip

According to the Huffington Post, San Diego Fire Department dispatcher Brian Anderson and his sister recently went on a seven-hour road trip. Anderson decided to provide hours' worth of entertainment – and annoyance – along the way by lip-syncing to everything from Mariah Carey to the Spice Girls to Blink-182. And no, his sister was not amused.

Earlier this month, Anderson posted a hilarious time-lapse video from the trip to YouTube. The footage quickly went viral, with more than 2.5 million views as of Monday morning. Check it out here.
