Heh, well, first, butt implants are rumored to be some of the most painful implants you can possibly have. So the chances she was awake were slim at best.
Second, butt implants are always a gel, and they are molded, not inflated. Part of the reason they are so painful is they can't insert a "flat" implant, then add fluid, so the incision is much larger than with breast implants.
On a side note, the recovery time from a butt implant is 6-8 weeks, where you are not supposed to even sit down for the first two weeks.
The story appears to be satorical in nature anyway, what doctor is that much of an ass? If she wants J'Lo, lets give it to her? Sounds like sound medical advice to me.
