This is almost better than a sackful of candy! And it certainly provides three minutes and 15 seconds of yummy eye (and ear) candy. Behold, the new Halloween-themed video from "The Sing-Off" Season 3 winners Pentatonix, featuring a so-good-it's-scary a cappella cover of Imogen Heap's "Aha!" and even a cameo by "So You Think You Can Dance" Season 5 alum Kayla Radomski (whose "Addiction" dance was one of the spookiest "SYTYCD" routines ever):

After watching this, I just might go as Penatontix for Halloween. All I need is some neon legwarmers from their famous "Video Killed The Radio Star" performance, and I'll be set!
