This is Pentatonix.
I'm in love with them.
Aparently they were on some sort of like, singing show, but I don't have T.V. so I have no idea what anyone is talking about when they tell me this. My dad happened to post one of their videos on his facebook and this is my alltime favorite song of theirs.
BTW that is some sexy bass that dude with the black hair can pump out. It's the best in their Macklemore parody. DAT BASS
This video is super rad. People really are amazing
Also, here is a baby chameleon eating.
