star wars - What were the OTHER 8 times that Anakin saved Obi-Wan's skin before ROTS?

From Obi-Wan and Anakin's dialog in ROTS:

ANAKIN: All right. But you owe me . . . and not for saving your skin for the tenth time . . .
OBI-WAN: Ninth time . . . that business on Cato Nemoidia doesn't count. I'll see you at the briefing.

What were the OTHER 8 times that Anakin saved Obi-Wan's skin?

Thanks to Jared's last question for giving me the impulse to ask this.
