Hmm.. How to get 50 thieving fast?

Currently 24.

Saw Hey321's Rogue Den Thiever, and decided I'd try to fix it up. I'd find it useful, even if no-one else did. So, again, I ask, what is THE fastest way to get 50?

Cake Stall.

That Al-Kharaid minigame is pretty awesome... however for something scriptable, I'd go for the Varrock tea stall as there are no guards at that one.
