This was an converstation split between Ventrilo and raid chat.
One of the raid members was asking for something besides Sanctuary, apparently unaware that he had all three pally buffs. My-brother-with-a-pally said something like 'What else do you want?!" and I barely hear someone else say 'How 'bout your sister?'.
At which point there was an aghast whisper of 'She in the RAID, dude!'
Hilarity ensued, and I did nothing but laugh. ;)
