I took this from someone on Rs Community, though it would be nice to post it here.

Well, I started this test with 48 thieving. Within 30 minutes, I hit 50. I was amazed. I kept going, and about another 30 minutes later, I was 52. I figured I'd test a bit, so I did. By wacking a level 41 bandit with my willow blackjack, I can pickpocket him 4 to 5 times before he gets up.
Exp Per Pickpocket ~ 67.5
Exp Per Knock Down (4 pickpockets) ~ 270
Exp Per Knock Down (5 pickpockets) ~ 337.5
Now I did this test going from 52 thieving to 53 thieving. That is right around 12,950 exp to level up. I started the clock at 9:51 pm (almost on the second). When my level up picture appeared, I looked at the clock to see it said 10:03 pm. 13 minutes to gain 12,950+ theiving exp!
I also recorded how many times the bandit caught me. He caught me 14 times, and I believe I used a total of 12 "super" kebabs (heal 8 normally). However that isn't accurate, because kebab's can heal more OR less.
With this new trick I have found, I not only gain easy exp, but if I keep at the same rythme, I could gain 90k-100k exp an hour. Lets just say I went from 48 thieving to 53 thieving in less than an hour. Dunno how long it took me exactly though.
