We've come across a lot of crazy music mash-ups on YouTube - some amazing, some hilarious, and some just plain weird - but this blend of Smash Mouth's 'All Star' and 'Take Me Home, Country Roads' by John Denver is both the best and worst thing ever.

Best because 'All Star' is the second dankest meme of all time behind Rickrolling, and worst because it somehow works so well and we don't know if we want to live in a universe in which that's possible.

Thank goodness this thing is only about 90 seconds long.

Godspeed, viewer.
