I just spent the past hour learning to juggle. I think I got the hang of it, and I was using limes!! It kind of reminded me of that episode of "King of Queens", when Doug is trained by Arthur to play ping-pong, but Arthur makes him use a wooden spoon because that way it would be easier once he played with a normal ping-pong paddle.
For some reason I think this logic also works in juggling :D I was going to use onions, but I kept dropping them and I didn't want to leave them bruised. The next best thing were the limes.
It's kind of addicting too, so I will continue to practice. I think hacky sacks would be just perfect! I just need two more.
