I am a juggler myself and i really enjoyed this video :D
Most of the tricks shown aren't the hardest ones,but its pretty hard to get it all synched to the music. I think the hardest trick is the one around 1:27

Also very nice contact juggling (or something like that) starting on 0:21

And the ''kick me'' sign on his back made me laugh

The ending is much harder than it looks,so overall this is a very awesome juggling act/routine :D

@shahil: yep, definitely real!  Michael Karas is well known in the juggling community, he's known for his creativity and theatrical-style juggling.

I met him at a convention a little while ago, he's a nice guy!  Learned some tricks from him =)

DAYUM!
