Tenacious D are a genius band, but they’re not really suitable for all to listen to. Some of the lyrics are downright dirty, but funny with it. Making them perfect for an impromptu serenading in the park.

This video shows a random, unknown guy playing a prank on a random, unknown couple lying in the park relaxing while simply enjoying each other’s company.

He approaches them stealthily, guitar in hand, and starts to sing F**k Her Gently by Tenacious D. I guess the tone of the song is easy to guess from the title.

Thankfully the couple take it in the right way, joining in and laughing along. I suspect there was a good chance of the opposite reaction, with the girl being offended and the guy jumping up ready for fisticuffs.
